Good to know
- US and UK gallons, pints and fluid ounces are different sizes; both are listed.
- Temperature isn't a simple multiplication, because the scales start at different points; the formula is shown with the result.
- Litres per 100 km works the other way round from miles per gallon: a lower number is better.
- You can type 1,5 or 1.5: both are read as one and a half.
