What is kg/m³ to lb/in³ Conversion

kg/m³ to lb/in³ conversion is a unit transformation for density, converting kilograms per cubic meter (kg/m³) to pounds per cubic inch (lb/in³). This conversion bridges the metric and imperial systems, commonly used in engineering, material science, and manufacturing. The conversion factor is derived from the relationships between kilograms and pounds (1 kg = 2.20462 lb) and cubic meters and cubic inches (1 m³ = 61023.7 in³), resulting in \(1 \, \text{kg/m³} \approx 0.0000361273 \, \text{lb/in³}\).

For example, a density of 1000 kg/m³ converts to 0.03613 lb/in³.

How to Convert kg/m³ to lb/in³

Conversion Formula: The density in lb/in³ is calculated as:

\(\rho_{\text{lb/in³}} = \rho_{\text{kg/m³}} \times 0.0000361273\)

Where:

• \(\rho_{\text{lb/in³}}\) = Density in pounds per cubic inch
• \(\rho_{\text{kg/m³}}\) = Density in kilograms per cubic meter

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

1. \(\rho_{\text{lb/in³}} = 1500 \times 0.0000361273 \approx 0.05419 \, \text{lb/in³}\).

Use the form above to input the density in kg/m³, and the calculator will convert it to lb/in³.

Density Units and Conversions

The calculator converts between the following density units:

• Kilograms per cubic meter (kg/m³): Base input unit
• Pounds per cubic inch (lb/in³): 1 kg/m³ ≈ 0.0000361273 lb/in³

Other common conversions include:

• 1 kg/m³ = 0.001 g/cm³
• 1 kg/m³ = 0.0624279 lb/ft³
• 1 lb/in³ ≈ 27679.9 kg/m³

Standard Density Examples

Some standard densities include:

• Water at 4 °C: \(\rho \approx 1000 \, \text{kg/m³} \approx 0.03613 \, \text{lb/in³}\)
• Gold: \(\rho \approx 19320 \, \text{kg/m³} \approx 0.69802 \, \text{lb/in³}\)
• Air at sea level: \(\rho \approx 1.225 \, \text{kg/m³} \approx 0.00004 \, \text{lb/in³}\)

FAQs

How do you convert kg/m³ to lb/in³?

To convert kg/m³ to lb/in³:

1. Take the density value in kg/m³.
2. Multiply by 0.0000361273 (since \(1 \, \text{kg/m³} \approx 0.0000361273 \, \text{lb/in³}\), based on 1 kg = 2.20462 lb and 1 m³ = 61023.7 in³).

What is the density of water in lb/in³ if it is 1000 kg/m³?

The density is \(1000 \times 0.0000361273 \approx 0.03613 \, \text{lb/in³}\).
