The density of mercury is 13800 kg / m3 What does this mean? Density of water 1000 kg / m3 convert to g / cm2

The density of mercury ρ = 13800 kg / m3 shows that if we take mercury in a volume of V = 1 m3, it will have a mass of m = 13800 kg.

The density of water ρ = 1000 kg / m3 shows that if we take water in the volume V = 1 m3, it will have a mass of m = 1000 kg.

1 kg = 100 g, 1 m3 = 1,000,000 cm3, therefore ρ = 1,000 kg / m3 = 1,000 * 1,000 g / 1 * 1,000,000 cm3 = 1 g / cm3.

This means that if we take water in a volume of V = 1 cm3, it will have a mass of m = 1 g. Or, water with a mass of m = 1 g will occupy a volume of V = 1 cm3.
