Assumptions used

What this answer assumes

Imperial gallons only. Use the US-gallon page when the source record is US liquid gallons.

The calculator uses the UK imperial gallon, where 1 imperial gal = 4.54609 litres.
It does not use the US liquid gallon; 1 US gal = 3.785411784 litres and gives a different answer.
Allowance is applied after conversion so measured imperial gallons and planning margin remain separate.
This is volume arithmetic only. Fuel, chemical, food, aquarium, brewing, medical or compliance decisions may require labelled containers, certified measuring equipment or official rounding rules.

Master’s Tip

How to use the result well

Master’s Tip: write “imperial gallons” on the report before converting. A plain “gallon” may be read as a US liquid gallon, which would understate the litre volume by about 17%.

Inputs

Imperial gallons: 5 imp gal

Method

Litres = imperial gallons × 4.54609. Optional planning litres = litres × (1 + allowance percent ÷ 100).

For 5 imperial gallons, multiply 5 × 4.54609 = 22.73045 litres. With a 5% allowance, planning volume is 22.7305 × 1.05 = 23.867 litres.

Assumptions

The calculator uses the UK imperial gallon, where 1 imperial gal = 4.54609 litres.
It does not use the US liquid gallon; 1 US gal = 3.785411784 litres and gives a different answer.
Allowance is applied after conversion so measured imperial gallons and planning margin remain separate.
