What is the conversion factor from g/mL to kg/m³?

Exactly 1000. One g/mL equals 1000 kg/m³. Water at 4 °C is the classic benchmark: 1.000 g/mL = 1000 kg/m³.

Why is the factor exactly 1000?

A cubic meter contains 1,000,000 milliliters (since 1 L = 1000 mL and 1 m³ = 1000 L). A kilogram equals 1000 grams. So 1 g/mL = 1000 g / (1,000,000 mL / 1,000,000) — working it out: 1 g/mL × (1 kg / 1000 g) × (1,000,000 mL / 1 m³) = 1000 kg/m³.

Is g/mL the same as g/cm³?

Yes. One milliliter equals exactly one cubic centimeter (1 mL = 1 cm³), so g/mL and g/cm³ are numerically identical and interchangeable in chemistry and medicine.

How do I convert g/mL to kg/m³ by hand?

Multiply the g/mL value by 1000. For example, 7.85 g/mL × 1000 = 7850 kg/m³ (carbon steel).

How do I convert kg/m³ to g/mL by hand?

Divide the kg/m³ value by 1000. For example, 2700 kg/m³ ÷ 1000 = 2.700 g/mL (aluminum alloy).

Where is g/mL commonly used?

g/mL is standard in chemistry, pharmacy, food science, and medicine. kg/m³ is used in engineering and physics. Converting between them is essential when combining data from different fields.

Summary

Convert density from grams per milliliter to kilograms per cubic meter instantly — 1 g/mL = 1000 kg/m³.

How it works

Enter a density value in the g/mL field to convert to kg/m³.
Or enter a value in the kg/m³ field to convert back to g/mL.
The result updates instantly as you type.
The formula is: kg/m³ = g/mL × 1000.
This works because 1 mL = 1 cm³, and 1 g/cm³ = 1000 kg/m³ by SI unit expansion.
