lb to in³

Density of some materials:

• Air ≈ 0.000043 lb/in³
• Aluminum ≈ 0.0975 lb/in³
• Concrete ≈ 0.0867 lb/in³
• Diesel ≈ 0.0307 lb/in³
• Gasoline (petrol) ≈ 0.02565 lb/in³
• Steel ≈ 0.2836 lb/in³
• Water (4°C) ≈ 0.03613 lb/in³

How to convert from in³ to lb?

The mass (weight) in pounds is equal to the volume in cubic inches multiplied by the weight in pounds per cubic inch.

Formula:

m = V x p

m – mass (weight) in pounds (lb);

V – volume in cubic inches (in³, cu in);

ρ – density in pounds per cubic inch (lb/in³, lb/(cu in), lb in^-3).

Example

Convert 2768 in³ to lb if the density is 0.03613 lb/in³.

Solution: m = V x p = 2768 x 0.03613 = 100 lb. Answer: 2768 in³ = 100 lb (density = 0.03613 lb/in³)
