How the Cubic Meters to Kilograms Converter Works
The Cubic Meters to Kilograms Converter multiplies m³ by 1,000 to get liters, then by density for kilograms. Type m³ straight into the input box.
Enter cubic meters
Type the volume in m³, such as a pool or tank capacity.
Enter the density
Type the density in kg/L.
Read kilograms
The result shows kg; divide by 1,000 for tonnes.
Check loads
Compare the mass with floor, vehicle or crane ratings.
Cubic Meters to Kilograms Converter Formula
The cubic meters to kilograms formula is kg = m³ × Density × 1,000, with density in kg/L.
- ρ
- Density in kg/L; 1 kg/L = 1 t/m³
Worked Examples
- Swimming pool (50 m³): 50 × 1.000 × 1,000 = 50,000 kg (50 t).
- Concrete slab (2.5 m³): 2.5 × 2.40 × 1,000 = 6,000 kg.
- Seawater ballast (300 m³): 300 × 1.025 × 1,000 = 307,500 kg.
Cubic Meters to Kilograms Converter Conversion Table
1 m³ of water weighs 1,000 kg (2,205 lb); 1 m³ of concrete weighs 2,400 kg. The table converts volumes into mass for 4 materials.

What is a Cubic Meters to Kilograms Converter?
A Cubic Meters to Kilograms Converter is a calculator that converts a volume in cubic meters into a mass in kilograms using density.
Designs, drawings and tank data give volumes in m³. Structural, lifting and transport checks need mass, so density bridges the two.
A cubic meter is a cube 1 m on each side. Filled with water, the cube weighs one metric tonne.
What are the Uses of a Cubic Meters to Kilograms Converter?
There are 4 main uses of a Cubic Meters to Kilograms Converter.
Structural loads
Engineers convert water tank and pool volumes into dead load.
Material ordering
Buyers convert m³ needed into tonnes priced.
Ship stability
Officers convert tank m³ into tonnes for loading plans.
Lifting plans
Riggers check the mass of filled hoppers and skips.
