Common Density Conversions

kg/m³ to g/cm³ kg/m³ → g/cm³
lb/ft³ to kg/m³ lb/ft³ → kg/m³
g/cm³ to lb/in³ g/cm³ → lb/in³
kg/m³ to lb/ft³ kg/m³ → lb/ft³

What is Density Conversion?

Density conversion is the process of converting measurements of mass per unit volume from one unit system to another. Our density converter tool makes it easy to switch between metric and imperial units used in scientific, industrial, and engineering applications.

Common units include kilograms per cubic meter (kg/m³), grams per cubic centimeter (g/cm³), and pounds per cubic foot (lb/ft³). Density is a fundamental property used in material science, geology, chemistry, fluid dynamics, and quality control processes.

Simply enter your value in the "From" field, select the original unit, choose your target unit in the "To" field, and the converter will instantly display the converted result along with the conversion formula.

Density Conversion Examples

Material Science Example

Comparing densities of common materials:

  • Water: 1000 kg/m³ = 1 g/cm³
  • Steel: 7850 kg/m³ = 7.85 g/cm³
  • Aluminum: 2700 kg/m³ = 2.7 g/cm³

Construction Example

Calculating concrete and aggregate densities:

  • Concrete: 2400 kg/m³ = 149.8 lb/ft³
  • Gravel: 1685 kg/m³ = 105.2 lb/ft³
  • Sand: 1600 kg/m³ = 99.9 lb/ft³

Oil and Gas Example

Converting petroleum density measurements:

  • Crude oil: 850 kg/m³ = 53.1 lb/ft³
  • Gasoline: 750 kg/m³ = 46.8 lb/ft³
  • Diesel: 850 kg/m³ = 53.1 lb/ft³

Frequently Asked Questions

How many kg/m³ in 1 g/cm³?

One gram per cubic centimeter equals exactly 1000 kilograms per cubic meter. This is a standard conversion, and water has a density of approximately 1 g/cm³ or 1000 kg/m³.

What is the formula for lb/ft³ to kg/m³?

To convert pounds per cubic foot to kilograms per cubic meter, multiply by 16.0185. For example, 100 lb/ft³ × 16.0185 = 1601.85 kg/m³.

How do I convert kg/m³ to lb/in³?

To convert kg/m³ to pounds per cubic inch, divide by 27679.9. For example, 8000 kg/m³ ÷ 27679.9 = 0.289 lb/in³.

What is the density of common substances in g/cm³?

Common densities in g/cm³: Water = 1.0, Aluminum = 2.7, Steel = 7.85, Gold = 19.3, Air = 0.0012, Wood (oak) = 0.6-0.9, Concrete = 2.4.

How does temperature affect density conversions?

Density changes with temperature because materials expand or contract. When performing precise conversions, always specify the temperature. Water reaches maximum density at 4°C (39.2°F) and decreases above and below this temperature.
