Convert lbs/ft³ to kg/m³ (Pounds per Cubic Foot to Kilograms per Cubic Meter)

1 lb/ft³ equals about

16.02 kg/m³

How to Convert lbs/ft³ to kg/m³

This is the inverse operation compared to the kg/m³ → lbs/ft³ conversion, and is useful for those starting from American technical specifications (for example a material's density reported in lbs/ft³ on a data sheet) who need to convert them to the International System for international projects or regulations.

The Conversion Formula

To convert a measurement from lbs/ft³ to kg/m³, simply multiply the value by 16.0185:

To convert from kg/m³ to lbs/ft³, perform the inverse operation, multiplying by 0.0624:

Practical Examples

• 62.4 lbs/ft³ ≈ 1,000 kg/m³ (density of water)
• 150 lbs/ft³ ≈ 2,402.8 kg/m³ (typical of concrete)
• 490 lbs/ft³ ≈ 7,849.1 kg/m³ (typical of steel)
• 30 lbs/ft³ ≈ 480.6 kg/m³ (typical of some lightweight woods)

When This Conversion Is Needed

This inverse conversion is essential for engineers and designers working on international projects or importing construction materials from the United States, where technical data sheets report density and other properties in the imperial system rather than metric units.
