How to convert imperial gallons to cubic meters
To convert a measurement in imperial gallons to cubic meters, multiply the value by 0.00454609. The conversion factor comes from the relationship between both units and the liter.
For example, to convert 5 imp gal to cubic meters: 5 × 0.00454609 = 0.02273045 m³.
What is a imperial gallon?
An imperial gallon is a British unit of volume equal to exactly 4.54609 liters, about 20% larger than the US gallon. The imperial gallon was defined in 1824 as the volume of ten pounds of water. It is still used in the UK and several Commonwealth countries, which is why UK 'miles per gallon' figures look higher than US ones.
Common uses of imperial gallons include: Fuel and fuel-economy figures in the UK and Canada; Historical and Commonwealth liquid measures; Comparing UK vs US gallon quantities; Agricultural and industrial liquid volumes.
What is a cubic meter?
A cubic meter is the SI unit of volume, equal to the space of a cube one meter on each side, or 1,000 liters. The cubic meter is the coherent SI derived unit of volume. It is the standard unit for large volumes in construction, water supply, and gas metering, where it is often shortened to 'cube' in the trades.
Common uses of cubic meters include: Water and natural gas utility billing; Concrete, soil, and bulk material ordering; Shipping container and cargo volume; Room and building air volume (HVAC).
