The mass of one cubic meter of water in kilograms is 1 kg.
This is a conversions case. First, we must determine how many cubic centimeters there are in a cubic meter. We have 1000 of these after conversion.
This essentially indicates that 1000 units of water, each with a volume of one cubic centimeter, would have to combine before we could create a cubic meter of water.
Knowing that one cubic centimeter weighs one gram, 1000 cubic centimeters would weigh 1000 * 1, or 1000g, or one kilogram.
Thus, 1 cubic meters of water will weigh 1 * 1000g = 1000g, or just 1 kg.
