About Liter
The liter is a metric unit equal to one cubic decimeter (0.001 m³). Science, global food labeling, and most countries’ everyday volumes use liters.
About Gallon (US)
The US liquid gallon is defined as 231 cubic inches (about 3.78541 liters). US recipes, fuel economy, and retail liquids typically use US gallons.
How to convert liters to gallons (us)
1 liter is equal to 0.2641720526373 gallon (us):
1 l = (1 L ÷ 3.78541178 L) gal = 0.2641720526373 gal
Each liter is defined as 1 L and each gallon (us) as 3.78541178 L, so one l equals 1 ÷ 3.78541178 gal = 0.2641720526373 gal.
Let V(l) be the numeric value of the same volume measured in Liter (l), and V(gal) the value in Gallon (US) (gal). Then:
V(gal) = V(l) × (1 / 3.78541178)
Equivalently, divide by how many l fit into one gal (liters per gal divided by liters per l):
V(gal) = V(l) ÷ 3.78541178
Or: gallon (us) = liter ÷ 3.78541178
Examples
Example #1: Convert 20 l to gallon (us)
20 l = 20 l × (1/3.78541178) gal = 5.2834410527 gal
20 l = 20 l ÷ 3.78541178 = 5.2834410527 gal
Example #2: Convert 50 l to gallon (us)
50 l = 50 l × (1/3.78541178) gal = 13.2086026319 gal
50 l = 50 l ÷ 3.78541178 = 13.2086026319 gal
Summary
To convert Liter to Gallon (US), multiply the value in l by the ratio of liters per l divided by liters per gal. Equivalently: value_gal = value_l × (1 / 3.78541178). Numerically, 1 l equals 0.26417205263729593 gal.
Relationship context
You are converting between metric (SI) (Liters) and US customary fluid / volume (Gallons (US)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 2.641721e-1.
