How it works
- Enter a value and pick the units you're converting from and to.
- The result updates instantly, alongside every other unit in the table below.
- Use Swap to flip the two units, or Copy next to any row to grab just that value.
The formula
Liters = Value × (unit's liter factor)
Result = Liters ÷ (target unit's liter factor)
Example: 1 US gallon to liters is 1 × 3.785411784 ≈ 3.79 L.
FAQ
Are these US or UK (imperial) units?
US customary units — a US cup, pint, quart, and gallon are all different from their UK imperial counterparts (a UK gallon is about 20% larger). If you need UK/imperial volumes specifically, double-check the conversion factor against a UK-specific source.
How precise are the cooking-measurement conversions (tsp, tbsp, cup)?
They use the exact US legal definitions (1 US cup = 236.5882365 mL, etc.), not rounded kitchen approximations — though real measuring cups and spoons vary enough in practice that exact precision rarely matters for cooking.
Does anything I type get sent anywhere?
No. The conversion is a simple multiplication done locally in your browser — nothing is uploaded.
Why is a liter used as the base unit internally?
Every unit is defined by how many liters it equals, so any conversion is just one multiply and one divide through that shared reference point, rather than needing a separate formula for every possible pair of units.

Handy for both a lab-style mL/L conversion and a recipe's cups/tablespoons, in the same table, instead of two separate lookups.
