How to use it

Using the volume converter

  1. 01

    Enter the amount

    Whole numbers or fractions-as-decimals both work.

  2. 02

    Pick source and target

    Mix kitchen measures and metric freely in either direction.

  3. 03

    Use the context rows

    See cups, fluid ounces and milliliters at a glance for recipe translation.

Good to know

US cups are not metric cups

A US legal cup holds 236.588 ml, Australian recipes use a 250 ml cup, and UK baking leans on weight. Converting a US recipe while assuming 250 ml cups inflates every wet ingredient by nearly 6%.

Gallons that differ by an ocean

This tool converts US gallons (3.785411784 L); the imperial gallon still used in Britain is 4.54609 L; about 20% bigger. That mismatch is exactly why the fuel-economy converter handles mpg separately.

Dry versus liquid

Historically US dry and liquid gallons differed slightly. This converter uses the liquid definitions that dominate cooking and commerce today.

How it's calculated

The math behind this calculator

result = value × factor(from) ÷ factor(to) Exact anchor: 1 US gallon = 3.785411784 L, 1 cup = 236.5882365 ml

All kitchen and liquid measures reduce to liters through exact US customary definitions; a teaspoon is 4.92892 ml because a gallon divides into 768 teaspoons. Metric units plug straight into the same table, so recipe scaling survives the transatlantic trip intact.

Assumptions & limitations

  • Results are rounded only for display; full precision is used internally.
  • Conversions use exact standard definitions of each unit.

Worked example

One US gallon of milk is 3.785 liters on any metric jug.

FAQ

Frequently asked questions

How many tablespoons are in a cup?
Sixteen US tablespoons make one US cup, since each tablespoon is three teaspoons and a cup is forty-eight teaspoons.
Are these US or imperial units?
All customary units here are US versions. Imperial pints and gallons are larger and intentionally excluded.
What about cubic centimeters?
One cc equals one milliliter exactly; enter the number in milliliters and the result is identical in cc.
