About this Volume Converter
This volume converter covers kitchen, fuel and tank measurements: litres and millilitres, both US and UK gallons (they are different sizes), cups, spoons and cubic metres. A cubic metre of water is exactly 1,000 litres, which makes it easy to work out tank and tanker quantities.
