The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]

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)

Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 mL of water is equal to approximately 100 g. Thus 100 mL of water is equal to approximately 100 g. Therefore, a solution with 1 g of solute dissolved in final volume of 100 mL aqueous solution may also be considered 1% m/m (1 g solute in 99 g water).
The finished syrup has a density of 66° on the Brix scale (a hydrometric scale used to measure sugar solutions). [38] The syrup is then filtered to remove precipitated "sugar sand", crystals made up largely of sugar and calcium malate. [39] These crystals are not toxic, but create a "gritty" texture in the syrup if not filtered out. [40]
However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.
Simple syrup (also known as sugar syrup, or bar syrup) is a basic sugar-and-water syrup. It is used by bartenders as a sweetener to make cocktails, and as a yeast feeding agent in ethanol fermentation. The ratio of sugar to water is 1:1 by volume for normal simple syrup, but can get up to 2:1 for rich simple syrup. [6]
