Conversions of density units
Density units conversion of ρ = m / V
This program converts English and American measures to metric units
 
 kilograms per cubic meter (kg/m³) 
= gram per liter (g/L or g/dm³) 
kilograms per liter (kg/L or kg/dm³) 
= tons per cubic meter (t/m³) 
 = grams per cubic centimeter (g/cm³)

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)

Water temperature  °C
 Water salinity (TDS)  mg/L or ppm
 
 
Water density ρ  kg/m3

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.
