About density conversion

How the g/ml to kg/m³ converter works

Density converts through kg/m³. 1 g/cm³ = 1 kg/L = 1,000 kg/m³ (water at 4 °C). 1 lb/ft³ = 16.0185 kg/m³ and 1 lb/US gal = 119.83 kg/m³. Concrete is about 2,400 kg/m³, steel 7,850 kg/m³, petrol about 740 kg/m³.

Frequently asked questions about density conversion

What is 1 g/mL in kg/m³?

1,000 kg/m³.

Is g/mL the same as g/cm³?

Yes — a milliliter is exactly one cubic centimeter.

What is ethanol's density?

0.789 g/mL.

What is seawater?

About 1.025 g/mL, slightly denser than fresh water.

Why does chemistry use g/mL?

Because laboratory volumes are in milliliters and the numbers land conveniently near 1.
