text: how would i convert kilograms to liters??? i need to know how to convert ex: 200 kilograms to liters it depends on the density of the material kilograms is a unit of measure of mass liters is a unit of measure of volume the ratio between mass and volume is the density  for water the density = 1000 kg / metercube  this means that 1 meter cube of water has a weight of 1000 kilograms  in liters >> 1 metercube = 1000 liters  this means 1 kilograms of water = 1 liter of water    i will give you a formula to convert any other material  volume[in liters] = volume[in metercube]*1000 volume[in metercube] = mass [in kilograms] / density [kg/m^3]   volume[in liters] = mass [in kilograms] / density [kg/m^3] *1000
