Frequently Asked Questions
How do I convert kg/m³ to lb/ft³?
Multiply the kg/m³ value by 0.0624279606. For example, 1,000 kg/m³ × 0.0624279606 = 62.428 lb/ft³.
What is water's density in both units?
Water is approximately 1,000 kg/m³, which converts to about 62.428 lb/ft³, a commonly cited reference point in both metric and US customary engineering contexts.
Why isn't the factor a round number?
It combines two independent exact definitions, the pound-to-kilogram ratio and the foot-to-meter ratio cubed (since volume scales as length cubed), neither of which is round on its own.
Related Density Converters
A good measuring tool marked in both kg/m³ and lb/ft³ removes the guesswork at the point of use.
