  2. Gram - Wikipedia

    en.wikipedia.org/wiki/Gram

    The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined in 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 °C ...

    The equivalent weights of the three acids 63.04 g, 204.23 g and 389.92 g respectively, and the masses required for the standardisation are 126.1 mg, 408.5 mg and 779.8 mg respectively.

    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. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .

  5. Gram per cubic centimetre - Wikipedia

    en.wikipedia.org/wiki/Gram_per_cubic_centimetre

    The gram per cubic centimetre is a unit of density in the CGS system, and is commonly used in chemistry.It is defined by dividing the CGS unit of mass, the gram, by the CGS unit of volume, the cubic centimetre.

  6. Relative density - Wikipedia

    en.wikipedia.org/wiki/Relative_density

    The gravitational force acting on the hydrometer is simply its weight, mg. From the Archimedes buoyancy principle, the buoyancy force acting on the hydrometer is equal to the weight of liquid displaced. This weight is equal to the mass of liquid displaced multiplied by g, which in the case of the reference liquid is ρ ref Vg.

  7. Mass fraction (chemistry) - Wikipedia

  9. Mixed liquor suspended solids - Wikipedia

    en.wikipedia.org/wiki/Mixed_liquor_suspended_solids

    The units MLSS is primarily measured in milligram per litre (mg/L), but for activated sludge its mostly measured in gram per litre [g/L] which is equal to kilogram per cubic metre [kg/m3]. Mixed liquor is a combination of raw or unsettled wastewater or pre-settled wastewater and activated sludge within an aeration tank.
