Formula
kg/m3 = value x unit factor (1 g/cm3 = 1,000 kg/m3, 1 lb/ft3 = 16.018463373960138 kg/m3)Understanding Density Conversion
Density is mass divided by volume. Pure water at about 4 degrees C has a density of roughly 1,000 kg/m3, which is 1 g/cm3 or 1 kg/L. Engineers often use kilograms per cubic meter, chemists use grams per milliliter, and US builders use pounds per cubic foot. Specific gravity is density relative to water, so for most purposes it equals density in g/cm3.
Tips and Best Practices
- 1g/cm3, g/mL and kg/L are all the same number.
- 2Multiply g/cm3 by 62.428 to get lb/ft3.
- 3Density changes with temperature, so quote it with a reference temperature when precision matters.
Real-World Example
Steel at about 7.85 g/cm3 is 7,850 kg/m3, which is 490 lb/ft3. Water at 1 g/cm3 is 62.43 lb/ft3.
Common Mistakes to Avoid
- Forgetting that 1 g/cm3 is 1,000 kg/m3, not 1.
- Mixing US and imperial gallons in lb/gal figures.
- Using a density at one temperature for a liquid heated well above it.
How to Use
- Pick the unit you have in the left selector and the unit you want in the right selector.
