See Water and Heavy Water for thermodynamic properties at standard condtions. Tabulated values are given below the figures, in SI and Imperial units. The figures show liquid and gaseous states at equilibrium as a function of temperature, starting at the triple point and ending at the critical temperature. The figures and tables below summarize the thermophysical properties of water and steam at equilibrium. At this equilibrium condition the vapor pressure is the saturation pressure. At higher pressures water would condense. The vapor pressure of water is the pressure at which water vapor is in thermodynamic equilibrium with its condensed state. If the space is confined the partial pressure exerted by the molecules increases until the rate at which molecules reenter the liquid is equal to the rate at which they leave. 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 / m 3 andġ kg/m 3 = 0.0624279605 pounds per cubic foot.Water tends to evaporate or vaporize by projecting molecules into the space above its surface. Ok, if you really need it: The density of water is roughly 62.4 lb per cubic foot. Some dinosours are still asking: What is the density of water in English units? Sea water has 30000 to 40000 ppm (parts per million) = mg/L salinity. The maximum density of pure water at a pressure of one standard atmosphere is 999.972 kg/m 3 at a temperature of 3.98 ☌ (277.13 K), that is 0.999 972 kg/L.Ĭalculation of water density (density of water H 2O) Water temperature Maximum density of pure water was 1.000 kg/L. Helium has a density of 0.1785 kg/m 3 = 0.1785 g/L = 0.0001785 kg/dm 3 = 0.0001785 kg/L =įrom 1901 to 1964, a litre was defined as exactly the volume of 1 kg of water at maximum density, and the Water has a density of 1000 kg/m 3 = 1000 g/L = 1 kg/dm 3 = 1 kg/L = 1 g/cm 3 = 1 g/mL. The correct SI unit of denstity of water is " ρ = 1000 kg/m 3". Water is the reference with its highest density at 3.98☌ ( ρ = 1 g/cm 3) Many people still use g/cm 3 (gram per cubic centimeter) or kg/L (kilograms per liter) to measure density. You can also enter the density in g/cm³, the mass in g, and the volume in cm³.ĭensity conversion factors from non-SI units Unit Please enter two values, the third value will be calculated. ![]() You will see the program but the function will not work.
