16 oz to mL: Convert a US Pint to Metric Volume

What 16 oz to mL Means for Americans

Sixteen fluid ounces is the size of a US pint, and it is one of the most common drink and container sizes in American life. Coffee shop cups, water bottles, beer glasses, and soup containers all cluster around that 16-ounce mark. But imported products, international recipes, and fitness apps all switch to milliliters, so converting 16 oz to mL keeps your portions and recipes accurate across both systems.

The answer is 473.18 mL. That figure is the bridge between the US pint and the metric system, and it appears on beverage labels, skincare bottles, and European recipes. Our fluid ounces to mL converter gives you the value instantly, but understanding the math helps you adapt any recipe or serving size with confidence.

The 16 oz to mL Formula

The conversion rests on one fixed value: one US fluid ounce equals 29.5735 milliliters. Because fluid ounces and milliliters are both units of volume, the conversion is a direct multiplication. You multiply the number of fluid ounces by 29.5735 to get the equivalent in milliliters.

16 oz Compared With Familiar Containers

Putting 473.18 mL next to common items makes the size clear. Sixteen fluid ounces equals one US pint, two US cups, 32 US tablespoons, or half a US quart. Those fractions matter in cooking, where 16 oz of stock or sauce is a standard batch size.

Practical Uses for the 16 oz to mL Conversion

The conversion matters most when you compare drinks and adapt recipes. If a European recipe calls for 500 mL of broth and your measuring cup is in fluid ounces, you know that 16 oz (473.18 mL) is slightly less than the target, so you top it up. The same logic applies to water, juice, oil, and any liquid an international source lists in milliliters.

It also helps with hydration and portion control. A 16-ounce water bottle is 473.18 mL, so hitting a daily goal of 2 liters means drinking about four and a quarter 16-ounce bottles. For packaged drinks, a 16-ounce serving equals 473.18 mL, which lets you compare with metric-labeled imports directly. For the smaller sibling size, see our guide to converting 8 oz to mL.

The conversion also comes up in fitness and meal prep. A 16-ounce shaker bottle holds 473.18 mL of water or protein shake, which is just under a half-liter, so two fills get you close to a liter of fluid. Soup recipes that call for a pint of broth translate to 473.18 mL, and smoothie bowls portioned at 16 ounces match the same figure. Knowing that 16 oz and 473 mL describe the same amount lets you move freely between American recipes and the metric labels on blenders, bottles, and food containers.

Converting 16 oz to Other US and Metric Units

Sometimes milliliters are not the most useful reference. Sixteen fluid ounces also equals 1 US pint, 2 US cups, 0.5 US quarts, or 0.125 US gallons. In metric units beyond milliliters, it is 0.47318 liters. That is just under half a liter, so two 16-ounce servings come close to filling a 1-liter bottle, a handy check when you portion drinks for a group.

For beer and brewing, note that a US pint is 16 fluid ounces, while a UK imperial pint is 20 imperial fluid ounces (568.26 mL). American bars pour the smaller US pint, so when a recipe or menu says a pint, assume 473.18 mL unless stated otherwise. To move between cups and milliliters for any value, our cups to mL converter covers the full range.

Tips for Accurate 16 oz Conversions

A few habits keep conversions reliable. Confirm you are using the US fluid ounce factor of 29.5735, not the imperial 28.4131, unless the source is British. Remember that a US pint (16 fl oz) is smaller than a UK imperial pint (20 fl oz), so the two are not interchangeable despite sharing the name pint.

Keep volume and weight separate. Sixteen fluid ounces of water weighs about one pound, but 16 fluid ounces of syrup or oil weighs more, and the milliliter equivalent is always a volume figure. When a recipe says 16 oz, check whether it means fluid ounces by volume or ounces by weight before you measure, since the difference changes the result and can throw off a recipe or a nutrition estimate. A quick label check saves the guesswork and keeps your conversions honest.
