Frequently asked questions
Which Volume units are supported?
The directory lists 44 units, including symbols and availability. Choose any source unit to browse its target units.
how to convert US gal to L?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 3.785411784 ≈ 3.785412 Liters. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Are US and imperial gallons interchangeable?
No. One US liquid gallon is exactly 3.785411784 litres, while one imperial gallon is exactly 4.54609 litres. US dry measures use another definition.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
