Enter any volume

Try 10 L, 2 US gal, 2 Imperial gallons, 1 1/2 L, or 7,5 litres. Unqualified “gal” is treated as ambiguous.
Display precisionExact math underneath
The gallon-size gap An Imperial gallon is about 20.10% larger than a US liquid gallon, so the same number of litres produces fewer Imperial gallons.

10 L ÷ 3.785411784 = 2.64172 US gal
Formula used US gal = litres ÷ 3.785411784
US vs Imperial at this volume

10 L = 2.6417 US gal or 2.1997 Imperial gal. The difference is caused by the gallon definition, not rounding.
