5 gallons is circa 19 liters. So when the liquid is water, then you don’t need to use the 100 ml container. 1 liter of water weights 1 kilogram, so put the 5 gallons bucket on a scale and pur in 19 kilograms of water.

100 ml is pretty easy to use. You can multiply it or divide it evenly without having to think at all.
