A 1 oz measuring cup is a handy size for portioning small amounts of liquid, medication, coffee, or craft materials. The right choice depends on how you plan to use it: a bulk pack of disposable-style medicine cups suits frequent portioning, while a reusable plastic beaker or stainless steel scoop may fit kitchen and hobby tasks better. These five options hold about 30 ml, but they differ in material, markings, quantity, and intended use.

| Dynarex 1 oz Medicine Cups | Plastic medicine cup | 100 | Double-sided CC and ML graduations |
| RyanDesign 30 ml Measuring Cups | Plastic graduated beakers | 10 | Food-grade plastic; handles hot liquids up to 212°F |
| Knupp Co. 1/8 Cup Stainless Steel Measure | Metal scoop | 1 | Engraved 1/8-cup and 30 ml markings |

Our Picks: Best 1 Oz Measuring Cups reviews
1. Dynarex 1 oz Medicine Cups: Best for Bulk Medication Portioning
The Dynarex cup is a small, 1 oz medicine cup sold in a box of 100. Its main purpose is measuring and taking small amounts of medication, such as liquid medicine. The curved lip is designed to make drinking from the cup easier.
The cups are made from virgin polypropylene, which the product description says improves clarity and flexibility. Graduations appear on both sides in CC and ML, with markings from 2.5 through 30. The markings are etched into the plastic rather than printed, which may help them remain readable with regular handling.
This bulk pack makes sense when you need many small portions on hand. The cups are non-sterile, so they are not a substitute for sterile measuring supplies when a sterile item is needed. They are also a more specialized choice than a kitchen measuring cup; the listing focuses on medication use rather than food preparation.
Pros:
- Pack of 100 is useful for frequent portioning.
- Double-sided CC and ML graduations are etched into the cup.
- Flexible polypropylene construction is designed to reduce the risk of spills.
- Curved lip can make drinking from the cup easier.
Cons:
- Non-sterile, so it is not suitable when sterile cups are required.
- Designed mainly for medication, not as an all-purpose kitchen measure.
Verdict: Choose the Dynarex cups if you need a large supply of clearly graduated 1 oz medicine cups; for reusable kitchen or craft measuring, consider one of the other options.
2. RyanDesign 30 ml Measuring Cups: Best Multi-Use Plastic Set
This 10-pack of mini plastic beakers is made for measuring small amounts across kitchen, lab, and craft tasks. Each cup has dual scales in milliliters and ounces, with markings listed as 5–30 ml and 7.5–27.5 ml. That range gives you several measurement steps in a compact cup.
The product description identifies the material as BPA-free, food-grade plastic and says the cups can handle hot liquids up to 212°F. A wide base and anti-slip edge are intended to help keep a cup steady during pouring, while the stackable shape is useful if you want to store several together. The listing also describes the plastic as flexible and crack-resistant.
Compared with the medicine-cup bulk pack, this set is positioned for a wider mix of uses, including cooking, resin, paint, and cosmetics. The main trade-off is that the cups are still small plastic beakers: they may not feel as substantial as a metal scoop, and the buyer should check the printed scale carefully when precise amounts matter.
Pros:
- Ten cups provide several measures for separate tasks.
- Dual ml and oz scales cover small measurement increments.
- Stackable design helps save storage space.
- Product description states that the cups handle liquids up to 212°F.
Cons:
- Plastic may not be the preferred feel for shoppers seeking a rigid metal measure.
- The listed scales use two different measurement ranges, so check the markings before pouring.
Verdict: Pick the RyanDesign set if you want multiple small graduated cups for varied kitchen and hobby tasks, especially when stackable storage and heat tolerance are useful.
3. Knupp Co. Stainless Steel Measure: Best for a Durable Kitchen Scoop
Unlike the graduated beakers, this Knupp Co. measure is a handled stainless steel scoop. It holds 1/8 cup, also marked as 30 ml, and is intended for both wet and dry ingredients. The product description highlights uses such as coffee, tea, flour, sugar, oils, spices, protein powder, and pet food.
The measurement marks are deeply etched rather than printed, and the listing says they remain legible through repeated dishwasher cycles. Its flat bottom and handle are practical for scooping from a container, while the compact shape can fit in a drawer or canister. The metal construction also makes it a different kind of tool from a clear cup: it is better suited to scooping than watching liquid rise against a graduated wall.
This is a single measure, so it is less useful if you need several cups at once. It also does not list multiple intermediate graduations like the plastic beakers. For a straightforward 1 oz scoop used often in a kitchen, though, its etched markings and dishwasher-safe design are appealing features.
Pros:
- Stainless steel construction is described as resistant to rust, corrosion, and staining.
- Engraved markings show both 1/8 cup and 30 ml.
- Dishwasher-safe according to the product description.
- Handle and flat bottom support scooping dry or wet ingredients.
Cons:
- Sold as a single cup rather than a multi-piece set.
- No graduated side scale for measuring amounts below its full capacity.
Verdict: Choose the Knupp Co. scoop if you want one sturdy, dishwasher-safe 1 oz kitchen measure for coffee and other ingredients rather than a beaker for graduated pouring.
4. EMUTOL Stainless Steel Measure: A Simple Hanging Storage Option
The EMUTOL is another single stainless steel scoop with a 1/8-cup capacity, equivalent to the listed 30 ml or 1 oz measure. Its handle is engraved with the measurements, and a hole at the end allows it to be hung up for storage. It is intended for both wet and dry ingredients, including coffee, flour, and oil.
The smooth surface is described as easy to clean with a damp cloth. The handle gives you leverage for scooping from jars or containers, while its compact size should make it easy to keep near frequently used ingredients. Like the Knupp Co. option, it is a fixed-capacity scoop rather than a graduated vessel for measuring several smaller amounts.
The main distinction between these two metal options is the EMUTOL’s hanging hole and its stated wipe-clean care. The product description does not specify dishwasher safety, so shoppers who want a measure they can put in the dishwasher may prefer the Knupp Co. model, which does list that feature.
Pros:
- Engraved handle shows 1/8 cup and 30 ml.
- Hanging hole offers an easy storage option.
- Suitable for scooping wet or dry ingredients.
- Smooth surface is described as easy to clean.
Cons:
- One fixed-capacity scoop does not provide smaller graduated markings.
- Dishwasher safety is not specified in the product description.
Verdict: The EMUTOL is a good fit if you want a compact metal scoop with engraved markings and a handle that can hang from a hook.
5. KeCool 30 ml Plastic Cups: Best for Reusable Graduated Measuring
KeCool’s small clear plastic cups are designed for measuring and mixing liquids, powders, and ingredients. The listing describes them as reusable and BPA-free, with dual scales on each cup: 5–30 ml on one side and 7.5–27.5 ml on the other. That makes them more versatile for partial amounts than a metal scoop that only measures its full capacity.
The cups are described as heat-resistant up to 212°F and stackable for storage. Their flexible plastic construction is intended to avoid shattering like glass, and the listing suggests cleaning with water or using an alcohol wipe for stubborn residue. The product description names kitchen, painting, lab, craft, and makeup uses, giving them a broader role than a medication-only cup.
The main practical question is how many cups come in the package: the supplied product information does not state a pack size. The plastic design is also not as rigid as stainless steel, and the listed graduation increments may not meet every need for highly precise work. Check the scale and the package details before ordering if quantity is important.
Pros:
- Dual scales provide several small measurement increments.
- Reusable plastic is described as BPA-free and heat-resistant up to 212°F.
- Stackable cups help reduce storage clutter.
- Listed for kitchen, craft, lab, and other small-volume tasks.
Cons:
- Pack quantity is not specified in the supplied product information.
- Flexible plastic may not feel as rigid as a metal measure.
Verdict: Choose the KeCool cups if you want clear, reusable beakers with multiple graduations for small-volume measuring across food and craft projects.
How to Choose the Best 1 Oz Measuring Cup
Match the cup to what you are measuring
Start with the task. Medicine cups are made for portioning small amounts of medication, while graduated beakers can suit liquids, ingredients, and craft materials. A stainless steel scoop is more practical for scooping coffee, flour, or other ingredients from a container. Think about whether you need to pour, scoop, or drink directly from the cup.
Choose between a graduated cup and a fixed-size scoop
A graduated cup has markings for measuring amounts below its full capacity, which can be useful when a recipe or project calls for only part of an ounce. A 1/8-cup metal scoop measures its set capacity and does not offer the same smaller increments. For measuring partial amounts, look for clear graduations in the units you use most.
Check the measurement units and markings
One fluid ounce is approximately 30 ml, and these products use 30 ml or 1/8 cup to describe the same general capacity. If you switch between units, choose a cup with both metric and ounce markings. Etched or engraved markings can be easier to maintain than printed markings, but it is still important to check that the scale is easy for you to read.
Consider the material and heat limits
Plastic cups are lightweight and may be easier to use for mixing or pouring. Some options in this list are described as reusable and heat-resistant up to 212°F, but do not assume that every plastic cup has the same heat limit. Stainless steel offers a more rigid scoop design, but it does not provide a clear side wall for viewing liquid levels.
Think about quantity and storage
A large pack can be useful when cups are needed often or for several people, while a single metal scoop may be enough for a regular kitchen routine. Stackable plastic cups can save cabinet or drawer space. If you prefer to hang tools, look for a handle with a hanging hole. Check package quantity before ordering, especially when the listing details are not clear.
Consider cleaning and intended use
Cleaning guidance varies by product. One metal option is listed as dishwasher safe, while another is described as easy to wipe clean; plastic products may have different care instructions. Also check whether a cup is intended for medication, food, or craft use. A non-sterile medicine cup should not be treated as sterile, and a product intended for one purpose should not automatically be assumed suitable for every other task.
Frequently Asked Questions
Is 1 oz the same as 30 ml?
One US fluid ounce is approximately 29.57 ml, so product listings commonly round it to 30 ml. The products here use 30 ml as the metric equivalent for a 1 oz measure.
Is 1/8 cup equal to 1 oz?
For US volume measures, 1/8 cup equals 1 fluid ounce. That is why the stainless steel scoops in this list are marked as both 1/8 cup and 30 ml.
Which type is better for medication?
The Dynarex option is specifically described as a medicine cup and includes CC and ML graduations. It is non-sterile, so use a sterile cup when a healthcare professional or product directions require one.
Can I use these cups for hot liquids?
The RyanDesign and KeCool product descriptions state that their plastic cups can handle temperatures up to 212°F. The supplied information does not give the same heat limit for every cup, so check the specific product details before using another model with hot liquid.
Which option is best for coffee?
The Knupp Co. and EMUTOL stainless steel scoops are both described for measuring coffee. The Knupp Co. listing also specifies dishwasher-safe cleaning, while the EMUTOL has a hole in its handle for hanging storage.
Do the plastic cups have markings for less than 1 oz?
Yes. The RyanDesign and KeCool descriptions list graduations below their 30 ml capacity. The Dynarex medicine cup also has multiple CC and ML markings, from 2.5 through 30.
Which option should I choose for crafts?
The RyanDesign and KeCool plastic cups are both listed for craft uses such as resin, paint, or other small-volume mixing tasks. Choose based on the scales, package details, and heat or cleaning needs that matter for your project.
Final Recommendation
For a bulk supply of medication cups, the Dynarex pack stands out for its etched CC and ML graduations and curved lip. For reusable measuring across kitchen and craft tasks, the RyanDesign and KeCool plastic beakers offer graduated scales, while the Knupp Co. and EMUTOL stainless steel scoops are better suited to repeated scooping. Choose the style that matches how you will measure most often, and check the product’s quantity and care details before buying.
