What is kg/m³ to lb/ft³ Conversion

kg/m³ to lb/ft³ conversion is a unit transformation for density, converting kilograms per cubic meter (kg/m³) to pounds per cubic foot (lb/ft³). This conversion bridges the metric and imperial systems, commonly used in engineering, construction, and material science. The conversion factor is derived from the relationships between kilograms and pounds (1 kg = 2.20462 lb) and cubic meters and cubic feet (1 m³ = 35.3147 ft³), resulting in \(1 \, \text{kg/m³} \approx 0.0624279 \, \text{lb/ft³}\).

For example, a density of 1000 kg/m³ converts to 62.43 lb/ft³.

How to Convert kg/m³ to lb/ft³

Conversion Formula: The density in lb/ft³ is calculated as:

\(\rho_{\text{lb/ft³}} = \rho_{\text{kg/m³}} \times 0.0624279\)

Where:

• \(\rho_{\text{lb/ft³}}\) = Density in pounds per cubic foot
• \(\rho_{\text{kg/m³}}\) = Density in kilograms per cubic meter

Example Calculation: For a density of 1500 kg/m³:

1. \(\rho_{\text{lb/ft³}} = 1500 \times 0.0624279 \approx 93.64 \, \text{lb/ft³}\).

Use the form above to input the density in kg/m³, and the calculator will convert it to lb/ft³.

Density Units and Conversions

The calculator converts between the following density units:

• Kilograms per cubic meter (kg/m³): Base input unit
• Pounds per cubic foot (lb/ft³): 1 kg/m³ ≈ 0.0624279 lb/ft³

Other common conversions include:

• 1 kg/m³ = 0.001 g/cm³
• 1 kg/m³ = 0.001 kg/L
• 1 lb/ft³ ≈ 16.0185 kg/m³

Standard Density Examples

Some standard densities include:

• Water at 4 °C: \(\rho \approx 1000 \, \text{kg/m³} \approx 62.43 \, \text{lb/ft³}\)
• Gold: \(\rho \approx 19320 \, \text{kg/m³} \approx 1206.34 \, \text{lb/ft³}\)
• Air at sea level: \(\rho \approx 1.225 \, \text{kg/m³} \approx 0.08 \, \text{lb/ft³}\)

Use this calculator to convert these values or your own measurements.

FAQs

How do you convert kg/m³ to lb/ft³?

To convert kg/m³ to lb/ft³:

1. Take the density value in kg/m³.
2. Multiply by 0.0624279 (since \(1 \, \text{kg/m³} \approx 0.0624279 \, \text{lb/ft³}\), based on 1 kg = 2.20462 lb and 1 m³ = 35.3147 ft³).

What is the density of water in lb/ft³ if it is 1000 kg/m³?

The density is \(1000 \times 0.0624279 \approx 62.43 \, \text{lb/ft³}\).
