FAQ

How many gallons is 18 liters?

18 L ≈ 4.755 gal

What is the formula to convert 18 L to gallons?

Divide the liter value by 3.785411784, the exact size of a US liquid gallon: 18 L ÷ 3.785411784 ≈ 4.755 gallons. That figure follows from the gallon's legal definition of 231 cubic inches.

How do I convert 4.755 gallons back to liters?

Multiply by 3.785411784: 4.755 gal × 3.785411784 ≈ 18 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 18 L gives about 4.755 gal by US measure but only about 3.959 gal by imperial measure — which is why UK and US miles-per-gallon figures cannot be compared directly.
