How many gallons is 81 liters?

81 L ≈ 21.398 gal

What is the formula to convert 81 L to gallons?

Divide the liter value by 3.785411784, the exact size of a US liquid gallon: 81 L ÷ 3.785411784 ≈ 21.398 gallons. That figure follows from the gallon's legal definition of 231 cubic inches.

How do I convert 21.398 gallons back to liters?

Multiply by 3.785411784: 21.398 gal × 3.785411784 ≈ 81 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 81 L gives about 21.398 gal by US measure but only about 17.818 gal by imperial measure — which is why UK and US miles-per-gallon figures cannot be compared directly.
