Density and Specific Gravity Converter

What is this density in other units, or as a specific gravity?

Convert density between kg/m³, g/cm³, kg/L, lb/in³, lb/ft³, lb/US gal and specific gravity (relative to water at 4 °C).

Density valueThe density or specific gravity as written on the data sheet.
Unit of the entered valuechoiceIts unit.

Method and formulas

  1. Factors to kg/m³: g/cm³ and kg/L × 1000; lb/in³ × 27 679.9047; lb/ft³ × 16.0184634; lb/US gal × 119.826427; specific gravity × 999.972 (water at 4 °C).
  2. Example: 7.85 g/cm³ = 7,850 kg/m³ = 0.283599 lb/in³.

Limitations

  • Specific gravity is referenced to water at 4 °C; some data use 15.6 °C (60 °F) water, which differs slightly.
  • Example values are illustrations. Replace them with values for your actual task.

Typical uses

  • Convert material data between unit systems
  • Turn specific gravity into density for mass calculations

Who it is for

  • Engineers
  • Technicians
  • Buyers and estimators

What you get

  • Density in each unit
  • Specific gravity

Interpreting the result

  • Use the density at the working temperature for liquids.
