m3 to kg – cubic meters to kilograms – mass to volume online

Volume in cubic meters (m³, cu m):

Density in

Mass (weight) in kilograms (kg):

0.00kg

kg to m3

Density of some materials:

  • Air ≈ 1.2 kg/m3
  • Aluminum = 2700 kg/m3
  • Concrete ≈ 2400 kg/m3
  • Diesel ≈ 850 kg/m3,
  • Gasoline (petrol) ≈ 710 kg/m3
  • Steel = 7850 kg/m3
  • Water (4°C) = 1000 kg/m3

How to convert from m3 to kg?

The mass (weight) in kilograms is equal to the volume in cubic meters multiplied by the weight in kilograms per cubic meter.

Formula:

m = V x p

m – mass (weight) in kilograms (kg);

V – volume in cubic meters (m3, cu m);

ρ – density in kilogram per cubic meter (kg/m3, kg/(cu m), kg m-3).

 

Example

Convert 12 m3 to kg if the density is 1000 kg/m3.

Solution: m = V x p = 12 x 1000 = 12000 kg. Answer: 12 m3 = 12 000 kg (density = 1000 kg/m3)
