FAQ

How many gallons is 15 liters?

15 L ≈ 3.963 gal

What is the formula to convert 15 L to gallons?

Divide the liter value by 3.785411784, the exact size of a US liquid gallon: 15 L ÷ 3.785411784 ≈ 3.963 gallons. That figure follows from the gallon's legal definition of 231 cubic inches.

How do I convert 3.963 gallons back to liters?

Multiply by 3.785411784: 3.963 gal × 3.785411784 ≈ 15 liters. The sign is ≈ because the gallon figure on this page is rounded to three decimals.

Is this a US gallon or a UK gallon?

A US liquid gallon. The imperial gallon is 4.54609 L, about 20% larger, so the same 15 L gives about 3.963 gal by US measure but only about 3.3 gal by imperial measure — which is why UK and US miles-per-gallon figures cannot be compared directly.
