g/cm³ to kg/m³

Every materials datasheet speaks two languages. The PDF says 2.7 g/cm³ — aluminum, instantly readable. The structural analysis software on your desktop wants 2,700 kg/m³, and the difference between them is exactly 1,000, always, for every material. This page does that multiplication.

g/cm³ to kg/m³

Every materials datasheet speaks two languages. The PDF says 2.7 g/cm³ — aluminum, instantly readable. The structural analysis software on your desktop wants 2,700 kg/m³, and the difference between them is exactly 1,000, always, for every material. This page does that multiplication.

kg/m³ = g/cm³ × 1,000
1 g/cm³ = 1,000 kg/m³ — exact SI definition
The factor is exact — derived from SI definitions and the 1959 yard/pound agreement.

Engineering Context

Density links the mass and volume families on this site — it is their ratio. For the mass numerator, the kg to g and lbs to kg converters carry the same 1959 constants that appear here; for the volume denominator, the liters to mL and cubic feet to cubic meters pages supply the cubed lengths. The density hub collects all ten converters in this family.

Frequently Asked Questions

Is 1 g/cm³ the same as 1 kg/L?

Yes — 1 g/cm³ = 1 kg/L = 1,000 kg/m³, all exact. The liter is defined as 1,000 cubic centimeters, so a gram per cubic centimeter is a kilogram per liter. Water sits at 1 in all three.

Why does the FEA model want kg/m³?

Because the coherent SI unit keeps the math clean. When mass appears in kilograms and volume in cubic meters, forces land in newtons and pressures in pascals. g/cm³ is fine for reading a table; kg/m³ is right for computing with it.

Is the 1,000 factor ever not exact?

Never. The relationship is a definitional consequence of SI prefixes — a gram is 10⁻³ kilograms and a cubic centimeter is 10⁻⁶ cubic meters. There is no measured constant involved.
