Density Converter
Convert between different density units: kg/m³, g/cm³, lb/ft³, and more.
How to Use the Density Converter
Select your source and target density units, enter a value, and the converter will instantly show the result. Density measures how much mass is contained in a unit volume.
Common Density Units
- kg/m³ (kilogram per cubic meter): SI unit, commonly used in science and engineering
- g/cm³ (gram per cubic centimeter): Widely used for material density specifications
- lb/ft³ (pound per cubic foot): Used in the US and imperial systems
- lb/in³ (pound per cubic inch): Precise measurements for small volumes
Conversion Factors
1 g/cm³ = 1000 kg/m³ = 62.43 lb/ft³ = 0.036127 lb/in³
Density Conversion Example
Water has a density of 1 g/cm³. Convert to kg/m³:
- Result: 1 g/cm³ = 1000 kg/m³
Iron has a density of 7.87 g/cm³. In lb/ft³:
- Result: 7.87 g/cm³ ≈ 491 lb/ft³
Frequently Asked Questions
-
Density is the mass of a substance per unit volume. It tells you how tightly packed the molecules of a material are.
-
Water has a standard density of 1 g/cm³ or 1000 kg/m³ at 4°C. This is the reference density for all liquids and solids.
-
Different industries and countries use different units. Engineers, scientists, and manufacturers need to convert for calculations and specifications.
-
Oil is less dense than water (≈0.9 g/cm³), which is why it floats on water.
