Fluid-volume conversion
16oz to ml: Exact Conversion and Cup Size Guide
473.18 mLfor 16 U.S. fluid ounces
Sixteen U.S. fluid ounces is usually rounded to 473 mL. A 480 mL label uses a different convention, while imperial ounces and weight ounces require different calculations.
Quick answer
16 oz to mL at a Glance
The correct number depends on whether “oz” means U.S. liquid volume, imperial liquid volume, a food-label convention, or weight.
The Standard U.S. Answer
473.18milliliters, normally rounded to 473 mL. For the query “16oz to ml,” this is the practical answer when “oz” means U.S. fluid ounces.
| Meaning of 16 oz | Milliliters | When it applies |
|---|---|---|
| 16 U.S. fluid ounces | 473.18 mL | U.S. customary liquid measurement |
| Rounded U.S. fluid ounces | 473 mL | Recipes and everyday conversion |
| U.S. nutrition labeling | 480 mL | FDA household-measure convention |
| 16 imperial fluid ounces | 454.61 mL | U.K./imperial liquid measure |
| 16 ounces by weight | No single answer | The material’s density is required |
The underlying U.S. and imperial conversion factors are published in the NIST Guide to the SI.
Calculation method
How to Convert 16oz to mL
Multiply U.S. fluid ounces by 29.57353. Divide by the same factor to convert milliliters back to U.S. fluid ounces.
Fluid Ounces to Milliliters
16 × 29.57353 = 473.17648 mL
Rounded to two decimal places, the result is 473.18 mL. Rounded to the nearest whole milliliter, it is 473 mL.
Milliliters Back to Fluid Ounces
480 ÷ 29.57353 ≈ 16.23 U.S. fl oz
A 500 mL bottle is approximately 16.91 U.S. fluid ounces, so 500 mL is not the same as 16 fl oz.
Why answers differ
473.18, 473 or 480 mL?
All three numbers can appear in legitimate contexts. The difference is whether the source uses an exact customary conversion, everyday rounding, or U.S. food-label rules.
Customary conversion
473.18 mLSixteen U.S. fluid ounces using the NIST factor of 29.57353 mL per fluid ounce.
Everyday rounding
473 mLThe same U.S. customary value rounded to the nearest whole milliliter.
Nutrition labeling
480 mLThe FDA convention treats one fluid ounce as 30 mL for nutrition labeling.
The FDA serving-size guidance uses 30 mL per fluid ounce and 240 mL per cup for nutrition labeling. The difference between 473.18 and 480 mL is approximately 6.82 mL, or 1.4%.
Measurement systems
Cups, Pints, Imperial and Weight
Sixteen U.S. fluid ounces equals two U.S. cups and one U.S. liquid pint. Imperial volume and weight ounces follow different rules.

U.S. and imperial ounces differ
Sixteen U.S. fl oz is 473.18 mL; sixteen imperial fl oz is approximately 454.61 mL.
Do Not Mix Volume and Weight
Fluid ounce (fl oz) measures volume. A plain ounce (oz) can measure mass.
Sixteen weight ounces of flour, honey, oil, and water do not occupy the same volume. When density is known, use:
NIST lists one avoirdupois ounce as 28.34952 g, so 16 ounces by weight is 453.59232 g. That still does not establish volume until the material and density are known.

Packaging context
What 16 oz Means for a Paper Cup
For disposable drinkware, 16 oz is a nominal capacity label in the approximately 473–480 mL size class. It does not establish exact dimensions, working fill, wall construction, or lid fit.
These dimensions describe one reviewed PaperBull double-wall example, not every 16 oz cup. See the paper cup dimensions and dieline guide for supplier-specific 8–16 oz measurements.
Product routes
Choose a 16 oz Cup Construction
The volume label is only the starting point. Match the construction to the beverage, handling conditions, branding plan, and approved components.
General hot-drink route
Single-Wall Paper Cup
A paper-cup route for takeaway programs where the buyer controls the full cup, lid, and optional sleeve combination.
- Confirm handling comfort
- Check sleeve requirements
- Match the approved lid
Additional wall structure
Double-Wall Paper Cup
A separate hot-drink construction with an additional paper wall. Verify the exact drawing rather than transferring specifications from another family.
- Confirm formed dimensions
- Check dispensers and carriers
- Test the filled cup and lid
Kraft visual treatment
Kraft Double-Wall Cup
A kraft-finish route for buyers who want a different material appearance while retaining a supplier-confirmed double-wall structure.
- Review material appearance
- Check artwork contrast
- Approve a physical sample
Procurement check
Confirm More Than Capacity
Nominal capacity is a starting point. The usable cup-and-lid system must be checked around the actual drink and service workflow.
Verify the exact cup, capacity convention, working fill, and approved components.- Name the product and construction. Identify the exact SKU, material, and wall format.
- Confirm the capacity convention. Ask whether the value is nominal, brimful, or tied to a recommended fill.
- Record formed dimensions. Check rim, base, height, and taper.
- Test working fill. Allow for foam, toppings, ice, mixing, movement, and lid clearance.
- Match the approved lid. The 16 oz label alone cannot prove fit.
- Check the service system. Verify sleeves, dispensers, shelves, carriers, and equipment clearance.
- Use the exact artwork dieline. Do not create print files from outside dimensions.
- Approve physical samples. Test the complete system before bulk production.
Common questions
16 oz to mL FAQs
Quick answers separate exact liquid conversion from labeling, imperial volume, weight, and physical cup specifications.
How many mL is 16oz?
Sixteen U.S. fluid ounces is 473.18 mL, normally rounded to 473 mL. U.S. nutrition labeling may represent 16 fluid ounces as 480 mL.
Is 16 oz exactly 480 mL?
No. The exact U.S. customary conversion is 473.176473 mL. The 480 mL value follows the nutrition-label convention of 30 mL per fluid ounce.
Is 16 oz one pint or two cups?
Sixteen U.S. fluid ounces equals one U.S. liquid pint and two U.S. customary cups by volume. An imperial pint is different.
How many mL is 16 imperial oz?
Sixteen imperial fluid ounces is approximately 454.61 mL, using 28.41306 mL per imperial fluid ounce.
Are all 16 oz paper cups and lids interchangeable?
No. Capacity does not fix the cup geometry or lid profile. Match the lid to the exact cup code and test the filled system.
