Factor1 kg/m³ = 0.001 t/m³

Converter

kg/m³

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1t/m³

Rendered to 6 significant figures.

Formula

Formula
t/m³ = kg/m³ × 0.001

Multiply any value in kilograms per cubic metre by 0.001 to obtain the value in metric tonnes per cubic metre.

Worked example

Convert 1000 kg/m³ to t/m³.

  1. 01Start with 1000 kg/m³.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 t/m³.
Result1000 kg/m³ = 1 t/m³

FAQ

What is the conversion factor from kg/m³ to t/m³?
1 kg/m³ equals 0.001 t/m³. To convert, multiply the value in kilograms per cubic metre by 0.001.
How do I convert 1 kg/m³ to t/m³?
1 kg/m³ = 0.001 t/m³. For any value, multiply by 0.001.
How do I convert t/m³ back to kg/m³?
Divide by the same factor — or equivalently, multiply by 1000. So 1 t/m³ = 1000 kg/m³.
When would I need to convert kilogram per cubic metre to metric tonne per cubic metre?
Density conversions are critical for fluid property datasheets, hydraulic head calculations, and reconciling lab measurements (often g/cm³) with process simulator inputs (kg/m³).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
