FAQ

What is the conversion factor from lb/in³ to kg/dm³?
1 lb/in³ equals 27.6799 kg/dm³. To convert, multiply the value in pounds per cubic inch by 27.6799.
How do I convert 1 lb/in³ to kg/dm³?

How do I convert kg/dm³ back to lb/in³?
Divide by the same factor — or equivalently, multiply by 0.03612729. So 1 kg/dm³ = 0.0361273 lb/in³.
When would I need to convert pound per cubic inch to kilogram per cubic decimetre?
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).
