Volume conversion rates
1 Liter = 1000 Milliliters
1 Cubic Meter = 1,000,000 Milliliters
1 Cubic Yard = 0.764554858 Cubic Meters, so derived from 1 Yard = 0.9144 Meters, as per the International yard and pound agreement of 1959.
1 Imperial Gallon = 4.54609 Liters, as per the United Kingdom’s Weight and Measures Act of 1985.
1 US Liquid Gallon = 3.785411784 Liters, equalling 231 Cubic Inches, itself so derived from 1 Yard = 0.9144 Meters.
Volume is the measurement of a three dimensional space. Firstly, the SI unit of volume is the cubic meter. Likewise, the cubic meter of water is equal to a tonne. And so, a liter of water has a volume of a 10 centimeter-sided cube.
All imperial measurements are larger than their US counterparts, except for the fluid ounce.
