# Kilogram per meter cubed

The kilogram per meter cubed is the SI unit of density and is defined as the mass of a substance divided by the volume it occupies. The SI unit of density is the kilogram per meter cubed (kg/m^3). The density of a substance is its mass per unit volume.

### How many kg are in a meter cubed?

There is no precise answer to this question since the kilogram is a unit of mass and the meter is a unit of length. However, we can approximate the answer by assuming that a cubic meter of water has a mass of 1,000 kg. Therefore, 1 m3 of water would have a mass of 1,000 kg, and 1 kg of water would have a mass of 1/1000 m3.

##### How do you convert kg to CBM?

There is no standard conversion factor between kilograms and cubic meters (cubic feet or cubic yards would be a better unit of measure for volume), so you would need to calculate the volume of the object in question in cubic meters, then divide by the density of the object to get the mass in kilograms.

For example, lets say you have a box that is 1 meter long, 1 meter wide, and 1 meter tall. The volume of the box is 1 cubic meter. If the box is filled with water, the density of the water is 1,000 kg/m^3, so the mass of the water in the box is 1,000 kg. Is kg m3 a unit of density? No, kg/m3 is the SI unit of density. What is the weight of 1m3 sand? The weight of sand varies depending on the type of sand. For example, a cubic meter of beach sand weighs around 1,800 kg, while a cubic meter of dry sand weighs 1,600 kg. What is the weight of 1 cubic meter? 1 cubic meter of water weighs 1,000 kilograms.
