Cubic Meters to Kg Converter
Convert cubic meters (m³) to kilograms using the density of the material. This volume-to-mass converter is essential for construction, shipping, and material estimation. The formula is mass = volume × density.
How to Convert m³ to Kg
For example, 2 cubic meters of concrete: 2 m³ × 2400 kg/m³ = 4,800 kg (4.8 metric tons). The density varies significantly between materials — sand is about 1,600 kg/m³ while steel is 7,850 kg/m³.

Frequently Asked Questions
How many kg is 1 cubic meter of water?
1 cubic meter of water weighs 1,000 kg (1 metric ton) at 4°C.
How many kg is 1 cubic meter of concrete?
1 cubic meter of concrete weighs approximately 2,400 kg (2.4 metric tons). This varies based on the mix — lightweight concrete can be 1,800 kg/m³ while heavy concrete reaches 2,500 kg/m³.
How many kg is 1 cubic meter of sand?
1 cubic meter of dry sand weighs about 1,600 kg. Wet sand is heavier at approximately 1,920 kg per cubic meter due to water filling the gaps between grains.
How do I convert m³ to tons?
First convert m³ to kg using density, then divide by 1000. Formula: tons = m³ × density (kg/m³) ÷ 1000.
