Frequently Asked Questions

How accurate are these density conversions?

All conversions use standard published values with up to 12 significant figures. Metric-imperial conversions use NIST-standard conversion factors.

What’s the difference between kg/m³ and g/cm³?

1 g/cm³ equals 1000 kg/m³. The g/cm³ unit is more practical for many materials (water = 1 g/cm³), while kg/m³ is the SI standard unit.

When would I use slug/ft³?

Slug per cubic foot is used in some engineering fields, particularly in US customary unit systems involving mass and force calculations.

What is Earth’s mean density used for?

Earth’s average density (5.515 g/cm³) is used as a reference in planetary science and geophysics for comparing other celestial bodies.

How do I convert density to specific gravity?

Specific gravity is density divided by water’s density (1 g/cm³). First convert to g/cm³, then divide by 1 (for liquids/solids) or 0.001225 (for gases, using air density).
