As a more complex example, the concentration of nitrogen oxides (NO x) in the flue gas from an industrial furnace can be converted to a mass flow rate expressed in grams per hour (g/h) of NO x by using the following information as shown below: NO x concentration = 10 parts per million by volume = 10 ppmv = 10 volumes/10 6 volumes NO x molar mass

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 ...
A milligram of gold is sometimes referred to as a mil or mgg. Therefore, 1 AUG = 1 gg = 1000 mgg = 1000 mil, and 1 mil = 1 mgg = 0.001 gg = 0.001 AUG. This allows gold holdings and transfers to take place in tiny fractions of a gram (equivalent to a few cents).
The Taiwan tael is 37.5 g and is still used in some contexts. The Taiwan tael is derived from the tael or ryō (両) of the Japanese system (equal to 10 momme) which was 37.5 g. Although the catty (equal to 16 taels) is still frequently used in Taiwan, the tael is only used for precious metals and herbal medicines. [citation needed]
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The corresponding unit of measurement is sometimes expressed as "gram equivalent". [1]
[4] The grain was the legal foundation of traditional English weight systems, [5] and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass. [6]: C-6 The unit was based on the weight of a single grain of barley which was equal to about + 4 ⁄ 3 the weight of a single grain of wheat.
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.
