About Cubic Feet

The cubic feet is the volume of a cube one feet on a side (about 28.3168 liters). HVAC, construction, and US freight sometimes use cubic feet.

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.

How to convert cubic feet to gallons (uk)

1 cubic feet is equal to 6.22883545904283 gallon (uk):

1 ft3 = (28.316846592 L ÷ 4.54609 L) ukgal = 6.22883545904283 ukgal

Each cubic feet is defined as 28.316846592 L and each gallon (uk) as 4.54609 L, so one ft3 equals 28.316846592 ÷ 4.54609 ukgal = 6.22883545904283 ukgal.

Let V(ft3) be the numeric value of the same volume measured in Cubic Feet (ft3), and V(ukgal) the value in Gallon (UK) (ukgal). Then:

V(ukgal) = V(ft3) × (28.316846592 / 4.54609)

Equivalently, divide by how many ft3 fit into one ukgal (liters per ukgal divided by liters per ft3):

V(ukgal) = V(ft3) ÷ 0.16054365323589

Or: gallon (uk) = cubic feet ÷ 0.16054365323589

Examples

Example #1: Convert 20 ft3 to gallon (uk)

20 ft3 = 20 ft3 × (28.316846592/4.54609) ukgal = 124.576709181 ukgal

20 ft3 = 20 ft3 ÷ 0.16054365323589 = 124.576709181 ukgal

Example #2: Convert 50 ft3 to gallon (uk)

50 ft3 = 50 ft3 × (28.316846592/4.54609) ukgal = 311.441772952 ukgal

50 ft3 = 50 ft3 ÷ 0.16054365323589 = 311.441772952 ukgal

Summary

To convert Cubic Feet to Gallon (UK), multiply the value in ft3 by the ratio of liters per ft3 divided by liters per ukgal. Equivalently: value_ukgal = value_ft3 × (28.316846592 / 4.54609). Numerically, 1 ft3 equals 6.228835459042825 ukgal.

Relationship context

You are converting between US customary fluid / volume (Cubic Feet) and UK imperial fluid / volume (Gallons (UK)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 6.228835e+0.
