FAQ

What is the conversion factor from lb/ft³ to t/m³?
1 lb/ft³ equals 0.01601846 t/m³. To convert, multiply the value in pounds per cubic foot by 0.01601846.
How do I convert 1 lb/ft³ to t/m³?
1 lb/ft³ = 0.0160185 t/m³. For any value, multiply by 0.01601846.
How do I convert t/m³ back to lb/ft³?
Divide by the same factor — or equivalently, multiply by 62.42796. So 1 t/m³ = 62.428 lb/ft³.
When would I need to convert pound per cubic foot 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).
