Frequently asked questions
- Does it support L/100 km?
- Yes. L/100 km is an inverse measure and is converted with reciprocal maths, exactly as in the Unit Converter.
- Are US and Imperial gallons different?
- Yes — an Imperial gallon is about 4.546 L versus 3.785 L for a US gallon, so both are listed separately.
