The litre is often also used in some calculated measurements, such as density (kg/L), allowing an easy comparison with the density of water. One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL ...
1793: The grave (the precursor of the kilogram) was defined as the mass of 1 litre (dm 3) of water, which was determined to be 18841 grains. [11] 1795: the gram (1 / 1000 of a kilogram) was provisionally defined as the mass of one cubic centimetre of water at the melting point of ice. [12] 1799: The Kilogramme des Archives was manufactured as a ...
V – specific volume in cubic decimeters per kilogram (1 dm 3 is equivalent to 1 liter) ... Up to 99.63 °C (the boiling point of water at 0.1 MPa), at this pressure ...
Liquid water has a density of about 1 kg/dm 3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm 3. kilogram per cubic decimetre (kg/dm 3) gram per cubic centimetre (g/cm 3) 1 g/cm 3 = 1000 kg/m 3; megagram (metric ton) per cubic metre (Mg/m 3)
Water is the most abundant substance on Earth's surface and also the third most abundant molecule in the universe, after H 2 and CO. [23] 0.23 ppm of the earth's mass is water and 97.39% of the global water volume of 1.38 × 10 9 km 3 is found in the oceans. [84]
[16] [17] At the same time, work was commissioned to precisely determine the mass of a cubic decimetre (one litre) of water. [Note 1] [11] Although the decreed definition of the kilogram specified water at 0 °C—its highly stable temperature point—the French chemist Louis Lefèvre-Gineau and the Italian naturalist Giovanni Fabbroni chose to ...

One mole of sucrose (sugar) per kilogram of water raises the boiling point of water by 0.51 °C (0.918 °F), and one mole of salt per kg raises the boiling point by 1.02 °C (1.836 °F); similarly, increasing the number of dissolved particles lowers water's freezing point. [155]
