It depends on the temperature of the water. At 4 degrees Celsius fresh water has a density of 0.99997 kilograms per litre. At 100 degrees Celsius fresh water has a density of 0.9974 kilograms per litre. Water has a roughly a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.

The density of water is approximately 1 kilogram per liter at standard temperature and pressure (STP).
1000. kg/m3, by the way, is the standard unit for density in SI; in older units, gram/cm3 or kg/liter was often used; both give a numerical value of 1 for water.
1 kg of water is equal to 1 liter, as the density of water is 1 kg per liter. So, 1 kg of water is equivalent to 1 liter.
At a density of 1.73 kg per liter, there are approximately 7.59 pounds in one gallon. This can be calculated by converting the density to pounds per liter (1 kg = 2.20462 lbs) and then multiplying by the number of liters in a gallon (approximately 3.785).
The mass of a liter of water is equal to one kilogram. However, for other substances, the mass of a liter can vary depending on the substance's density.
One liter of water weighs approximately one kilogram, as water has a density of 1 kg/L.
To convert milligrams per liter (mg/L) to milligrams per kilogram (mg/kg) for sand, you need to know the density of sand to account for the volume change. Once you have the density, you can multiply the mg/L value by 1000 (since 1 liter of water is approximately 1 kilogram) and divide by the density of sand to get the mg/kg value.
