📐 How to Use

Set the From dropdown to the unit you have, for example Liter or Gallon (US), and type the amount in the box beneath it.
Set the To dropdown to the unit you want; the converted capacity is shown live in the result panel with the per-unit factor below.
Use the swap arrows between the two columns when you need the reverse conversion, then Copy to lift the result out.
Load a frequent pairing from the Common Volume Conversions cards, or pick any combination from the All Volume Conversions list to open its own converter and conversion table.

❓ Frequently Asked Questions

QHow many liters are in a US gallon?

A US gallon is 3.78541 liters. An imperial gallon is 4.54609 liters, roughly 20 percent larger, so a US gallon is 0.832674 imperial gallons. Both sit in the unit menus under separate names, because mixing them up throws any fuel or tank figure out by a fifth.

QHow many milliliters are in a cup?

A US cup is 236.588 milliliters, which is 8 US fluid ounces of 29.5735 milliliters each. That is the cup this converter uses. Metric recipes normally mean a 250 milliliter cup and British recipes an imperial cup of about 284, so check the source.

QWhat is 1 liter in US gallons?

One liter is 0.26417218 US gallons, so four liters come to 1.056689 gallons rather than a round one. In imperial gallons a liter is 0.21996925. A liter is also 1,000 milliliters, 1,000 cubic centimeters, and one thousandth of a cubic meter.

QWhy does 1 tablespoon show as 3.000008 teaspoons?

A tablespoon is exactly 3 teaspoons by definition. The converter stores each unit as a size in liters rounded to six figures, and dividing 0.0147868 by 0.00492892 leaves a remainder in the seventh digit. Rounded to any practical kitchen precision, the answer is 3.

ℹ️ About Volume Conversion

Volume is capacity, and no other quantity has as many units that share a name while differing in size. A US gallon is 3.78541 liters, but an imperial gallon is 4.54609, so a UK gallon holds about 20 percent more. US fluid ounces, pints and quarts are all smaller than the UK versions for the same reason, which quietly breaks older recipes. Cooking is its own minefield: a US cup is 236.588 milliliters, while metric recipes assume a 250 milliliter cup and an imperial cup is about 284.

This page covers 12 units, with US and imperial gallons listed as separate entries. The liter acts as the base, so an entry is multiplied by its unit's capacity in liters and divided by that of the unit you want. The answer is then rounded for display, to six decimals below 10 and four above. Conversion runs entirely in your browser.
