Liters to Gallons Converter

The gallon here is the US liquid gallon of exactly 3.785411784 liters, so 1 L comes out as 0.26417 gal. If the gallons you need are UK (imperial) gallons, the number is smaller: 1 L is about 0.21997 imperial gallons.

The gap is not a rounding detail. For the same volume, the US figure is about 20% higher than the imperial one. A 50 L tank reads 13.2086 US gallons but only about 10.9985 imperial gallons. Before you copy a result into a form, a spec sheet or a forum post, check which gallon the other side means.

Most people land on this page with a capacity printed in liters and a question asked in gallons. Typical cases, computed with the tool's US gallon:

Capacity is the full tank. For a fill-up from a quarter tank you need far less, so the fourth decimal rarely matters here.

• Divide by 4. Easy, but it comes out 5.36% low. 50 L ÷ 4 = 12.5 gal against the real 13.2086.
• Divide by 3.8. Only 0.38% low. 50 L ÷ 3.8 = 13.1579 gal, close enough for almost any everyday use.
• Multiply by 0.26. 1.58% low, handy on a phone calculator when you don't want to divide.

If you need imperial gallons in your head, divide by 4.5 instead. That uses a different gallon entirely, so don't mix the two shortcuts.

The result box shows 5 significant figures for values under 1 gallon, 4 decimals between 1 and 100, and 2 decimals from 100 up. So 2 L shows 0.52834, 200 L shows 52.8344 and 1,000 L shows 264.17. The copy button copies that rounded figure.

For fuel and water, one decimal is plenty. When you are scaling a mixing ratio, such as a concentrate measured per gallon, keep the full figure through the calculation and round only the final answer. Rounding at each step adds up.
