FAQ

What is the conversion factor from g/mL to lb/in³?
1 g/mL equals 0.03612729 lb/in³. To convert, multiply the value in grams per millilitre by 0.03612729.
How do I convert 1 g/mL to lb/in³?
1 g/mL = 0.0361273 lb/in³. For any value, multiply by 0.03612729.
How do I convert lb/in³ back to g/mL?
Divide by the same factor — or equivalently, multiply by 27.6799. So 1 lb/in³ = 27.6799 g/mL.
When would I need to convert gram per millilitre to pound per cubic inch?
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).
