About Gallon (UK)
The UK imperial gallon is defined as approximately 4.54609 liters. It is larger than the US liquid gallon and is used for fuel and drinks labeling in the UK.
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.
How to convert gallons (uk) to liters
1 gallon (uk) is equal to 4.54609 liter:
1 ukgal = (4.54609 L ÷ 1 L) l = 4.54609 l
Each gallon (uk) is defined as 4.54609 L and each liter as 1 L, so one ukgal equals 4.54609 ÷ 1 l = 4.54609 l.
Let V(ukgal) be the numeric value of the same volume measured in Gallon (UK) (ukgal), and V(l) the value in Liter (l). Then:
V(l) = V(ukgal) × (4.54609 / 1)
Equivalently, divide by how many ukgal fit into one l (liters per l divided by liters per ukgal):
V(l) = V(ukgal) ÷ 0.21996924829909
Or: liter = gallon (uk) ÷ 0.21996924829909
Examples
Example #1: Convert 20 ukgal to liter
20 ukgal = 20 ukgal × (4.54609/1) l = 90.9218 l
20 ukgal = 20 ukgal ÷ 0.21996924829909 = 90.9218 l
Example #2: Convert 50 ukgal to liter
50 ukgal = 50 ukgal × (4.54609/1) l = 227.3045 l
50 ukgal = 50 ukgal ÷ 0.21996924829909 = 227.3045 l
Summary
To convert Gallon (UK) to Liter, multiply the value in ukgal by the ratio of liters per ukgal divided by liters per l. Equivalently: value_l = value_ukgal × (4.54609 / 1). Numerically, 1 ukgal equals 4.54609 l.
Relationship context
You are converting between UK imperial fluid / volume (Gallons (UK)) and metric (SI) (Liters). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 4.546090e+0.
