Density units conversions conversion pound cubic foot inch kg m3 density of water, density, h2o, saline, salinity, salt, TDS, temperature (original) (raw)
Density = mass / volume ρ = m / V
Please enter two values, the third value will be calculated.
You can also enter the density in g/cm³, the mass in g, and the volume in cm³.

Density conversion factors from non-SI units
| Unit | Symbol | Equivalent SI value |
|---|---|---|
| pounds per cubic foot | lb / ft3 | 16.018 46 kg / m3 |
| slugs per cubic foot | slug / ft3 | 515.378 8 kg / m3 |
| pounds per cubic inch | lb / in3 | 27 679.90 kg / m3 |
Many people still use g/cm3 (gram per cubic centimeter) or kg/L (kilograms per liter) to measure density.
SI standard is kg/m3. 1 kg/dm3 = 1000 g/1000 cm3 = 1 kg/L.
Water is the reference with its highest density at 3.98°C (ρ = 1 g/cm3)
The correct SI unit of denstity of water is "ρ = 1000 kg/m3". 1 m3 = 1,000,000 cm3.
Examples: Solid - water - noble gas
Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.
Water has a density of 1000 kg/m3 = 1000 g/L = 1 kg/dm3 = 1 kg/L = 1 g/cm3 = 1 g/mL.
Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =
0.0001785 g/cm3 = 0.0001785 g/mL.
From 1901 to 1964, a litre was defined as exactly the volume of 1 kg of water at maximum density, and the maximum density of pure water was 1.000 kg/L. The maximum density of pure water at a pressure of one standard atmosphere is 999.972 kg/m3 at a temperature of 3.98 °C (277.13 K), that is 0.999 972 kg/L.
Calculation of water density (density of water H2O)
Sea water has 30000 to 40000 ppm (parts per million) = mg/L salinity.
TDS = Total Dissolved Solids, e.g. 3.5 % = 35 ppt = 35000 ppm.
Some dinosours are still asking: What is the density of water in English units?
Ok, if you really need it: The density of water is roughly 62.4 lb per cubic foot. The density of water varies somewhat with temperature and pressure, and is higher for salt water than fresh water, 1 pound per cubic foot = 16.0184634 kg / m3 and
1 kg/m3 = 0.0624279605 pounds per cubic foot.
