Convert cubic meters to metric tons for 16 materials including concrete, sand, gravel, and soil. Includes density reference, weight comparison bars, and US/imperial ton outputs.
Converting cubic meters to metric tons requires material density — the weight per unit volume. Water has a density of exactly 1,000 kg/m³, meaning 1 m³ of water weighs exactly 1 metric ton. Concrete is 2.4 times denser at 2,400 kg/m³, so 1 m³ of concrete weighs 2.4 tonnes.
This converter includes 16 pre-loaded materials commonly used in construction, landscaping, and engineering. Select the material, enter the volume in cubic meters (or the weight in metric tons for the reverse direction), and get instant results in metric tons, kilograms, pounds, US short tons, and imperial long tons.
The tool is essential for construction project managers ordering materials in metric units, mining engineers calculating ore volumes, and logistics planners determining payload weights for trucks and ships. The visual comparison bars show at a glance how different materials compare in weight for the same volume. It also helps estimate transport loads and prevent overweight dispatch plans before booking equipment.
Material density varies enormously — mulch at 400 kg/m³ is six times lighter than concrete at 2,400 kg/m³. This tool pre-loads accurate densities for 16 common materials and outputs weight in five different ton/weight units, saving time and preventing costly ordering mistakes in procurement and transport planning for complex projects.
Weight (kg) = Volume (m³) × Density (kg/m³) Metric Tons = kg ÷ 1,000 1 metric ton = 1,000 kg = 2,204.6 lb
Result: 16 metric tons
10 m³ × 1,600 kg/m³ = 16,000 kg = 16 metric tons = 17.6 US short tons. This is roughly a full dump truck load of dry sand.
Density links volume and weight. In the metric system, water at 4°C defines the baseline: 1 m³ = 1,000 kg = 1 metric ton. All other materials are compared to this. Materials denser than water (most rocks, metals, concrete) have densities above 1,000 kg/m³; lighter materials (wood, mulch) are below.
Knowing the density lets you calculate whether a truck will "cube out" (run out of volume) or "weigh out" (hit the weight limit) first. A dump truck with 10 m³ capacity carrying gravel (1,680 kg/m³) would hold 16.8 tonnes — likely within its gross vehicle weight rating. The same truck carrying steel scrap at 7,850 kg/m³ would be severely overweight long before filling the bed.
Natural materials like sand, gravel, and soil vary in density by region due to mineral composition, grain size, and moisture content. Published densities are averages. For accuracy in critical applications, weigh a known volume of the specific material from your local supplier.
About 2.4 metric tonnes. Standard concrete density is 2,400 kg/m³. Actual ready-mix values can vary slightly with aggregate and moisture content.
About 0.625 m³ for dry sand (1,600 kg/m³) or 0.52 m³ for wet sand (1,920 kg/m³).
A metric ton (tonne) = 1,000 kg = 2,204.6 lb. A US short ton = 2,000 lb = 907.2 kg. The metric ton is ~10% heavier.
About 1,680 kg (1.68 metric tons). This varies by gravel size and moisture.
No. Volume and weight are related by density, which differs for every material. You must specify the substance.
Dry soil: ~1,200 kg (1.2 t). Wet soil: ~1,600 kg (1.6 t). Highly variable depending on composition.
