Volume Converter

Common volume conversions

Unit	Equal to
1 tablespoon	3 teaspoons
1 fluid ounce	2 tablespoons
1 cup	8 fluid ounces
1 pint	2 cups
1 quart	2 pints (4 cups)
1 gallon	4 quarts (16 cups)
1 liter	1,000 milliliters (≈ 4.23 cups)

Why cooking measurements need converting so often

US recipes measure volume with cups, tablespoons, and teaspoons, while most of the world bakes and cooks by milliliters and liters and often by weight (grams) rather than volume at all for dry ingredients like flour or sugar. That difference means a recipe from a UK, Australian, or European food blog frequently needs converting before it makes sense in a US kitchen, and vice versa. This tool covers the US customary units teaspoon, tablespoon, fluid ounce, cup, pint, quart, and gallon alongside milliliters and liters, so you can convert in either direction.

A note on precision in baking

Volume conversions are exact for liquids, but US "cup" measurements of dry ingredients (flour, sugar, cocoa) can vary by up to 20% depending on how tightly the ingredient is packed or scooped. For baking where precision matters, many recipes now list both a cup measurement and a gram weight when a gram weight is given, it's the more reliable number to follow even after you've converted the liquid ingredients here.

FAQ

Does this use US or UK (imperial) measurements?
This tool uses US customary units. UK imperial cups, pints, and gallons are a different size a UK imperial pint (about 568 mL) is roughly 20% larger than a US pint (about 473 mL) so results won't match if you need true imperial conversions.

Why do recipes from other countries use different measurements?
Most of the world uses the metric system (milliliters and liters) for cooking, while the US primarily uses cups, tablespoons, and teaspoons this tool bridges the two.

How many milliliters are in a US tablespoon?
A US tablespoon is 14.7868 mL, and a US teaspoon is 4.92892 mL both slightly smaller than their metric-rounded equivalents (15 mL and 5 mL) that some measuring spoons use for simplicity.

Is a US cup the same everywhere in the US?
Yes, the US customary cup (236.588 mL) is standardized, but it's worth noting the US also has a separate, very slightly different "US legal cup" (240 mL) used on nutrition labels the difference is small enough to ignore for cooking.

How do I convert a recipe that lists grams of flour instead of cups?
This tool converts volume, not weight, so it can't convert grams of flour directly weight-to-volume depends on the ingredient's density. For flour, 1 cup is commonly estimated at 120-125 grams, but that's a separate conversion from anything shown here.

Why does 1 liter not equal exactly 4 cups?
A US cup (236.588 mL) doesn't divide evenly into a liter (1,000 mL) 1 liter is about 4.23 cups. This is a common rounding trap when scaling metric recipes up using US measuring cups.
