Convert kg/m³ to Metric t/m³ Instantly
Use this Kilograms per Cubic Meter to Metric Tons per Cubic Meter converter to change density from kilograms per cubic meter (kg/m³) into metric tons per cubic meter (t/m³). One metric ton, also called one tonne, equals exactly 1,000 kilograms, so the cubic-meter denominator stays unchanged and the numerical density is divided by 1,000.
Convert kg/m³ to metric t/m³, reverse t/m³ to kg/m³, calculate total material mass from density and volume, or compare common metric and U.S. density units.
Enter density in kg/m³ to get the exact metric-ton-per-cubic-meter equivalent.
Decimals are supported.
Multiply metric t/m³ by exactly 1,000 to return to kg/m³.
Multiply kg/m³ by m³ to estimate total kilograms and metric tons.
Convert density across kg/m³, metric t/m³, g/cm³, lb/ft³ and lb/yd³.
To convert kilograms per cubic meter to metric tons per cubic meter, divide the kg/m³ value by 1,000. Both units use the same cubic-meter denominator, so the volume part does not need to be converted. Only the mass unit changes from kilograms to metric tons.
Example: 2,400 kg/m³ ÷ 1,000 = 2.4 metric t/m³.
A density of 750 kg/m³ becomes 0.75 t/m³. A density of 1,850 kg/m³ becomes 1.85 t/m³. A density of 2,500 kg/m³ becomes 2.5 t/m³. The material's physical density is identical before and after conversion; only its numerical representation changes.
Kilograms become metric tons while the physical density remains the same.
No cubic-meter conversion is needed in the main kg/m³ to t/m³ formula.
The exact kilogram-to-tonne relationship makes this a simple decimal conversion.
Convert metric tons per cubic meter back to kg/m³ by multiplying by 1,000.
This responsive density table shows common kg/m³ values and their metric t/m³ equivalents. The direct metric conversion is exact.

350 ÷ 1,000 = 0.35 t/m³.
800 ÷ 1,000 = 0.8 t/m³.
1,450 ÷ 1,000 = 1.45 t/m³.
2,400 ÷ 1,000 = 2.4 t/m³.
2,650 ÷ 1,000 = 2.65 t/m³.
Both units describe mass per unit volume. A density of 1,600 kg/m³ means that one cubic meter of material has a mass of 1,600 kilograms under the conditions represented by the stated density. The exact same density can be written as 1.6 metric t/m³.
These density units are used for construction materials, aggregates, soils, liquids, manufactured products, storage calculations and engineering work. Actual measured density can vary with moisture, compaction, particle size, temperature, void content and composition. A converter changes the unit; it does not determine the correct material density for your project.
For the reverse calculation, multiply metric tons per cubic meter by 1,000. For example, 2.35 t/m³ × 1,000 = 2,350 kg/m³. The cubic-meter denominator is unchanged.
Example: 1.75 t/m³ × 1,000 = 1,750 kg/m³.
Density is not the same as total project mass. Multiply density in kg/m³ by volume in m³ to get total kilograms. Then divide that total by 1,000 to express the result in metric tons. For instance, 5 m³ of material at 1,800 kg/m³ has a total mass of 9,000 kg, or 9 metric tons.

A detailed SI-style density expression useful when kilogram-level values are convenient.
The same density expressed with the larger metric mass unit, making larger values shorter and easier to scan.
A useful metric relationship is 1,000 kg/m³ = 1 g/cm³, so the numerical value in g/cm³ is the same as the numerical value in metric t/m³. For example, 2,400 kg/m³ equals 2.4 g/cm³ and 2.4 t/m³.
For U.S. customary density, 1 kg/m³ is approximately 0.062428 lb/ft³. The multi-unit tool above performs the cross-system calculation automatically. For formal SI definitions and unit conventions, see the BIPM SI Brochure.
kg/m³ to metric t/m³ uses a larger mass unit, so divide by 1,000.
A metric ton is exactly 1,000 kg and is not the U.S. 2,000-pound short ton.
The main conversion keeps the same m³ denominator.
kg/m³ and t/m³ are mass-per-volume values. Multiply by volume for project mass.
The unit conversion is exact, but actual material density may change with moisture, compaction or composition.
