50-litre tank example
A container labelled 50 litres is 13.2086 US liquid gallons (50 ÷ 3.785411784). It is only 10.9985 imperial gallons (50 ÷ 4.54609). If you're matching Australian equipment to a US specification, use the US figure.
The nominal volume is not a guarantee of usable tank capacity, especially where expansion or headspace matters.
Rounding, accuracy and common mistakes
Two decimal gallons is usually enough for a tank or container comparison. Keep more precision for dosing, flow calculations or repeated batch totals, then round to the available measuring equipment.
Confirm that the destination expects US gallons before dividing by 3.785411784.
Precision example: 20 L÷3.785411784=5.283441…US liquid gallons. Display 5.28 USgal; imperial gallons use a different factor.
