Definition

for substance $X$ in a mixture, quotient of mass $m_{X}$ (ISO 80000-4: Mechanics) of substance $X$ and volume $V$ (ISO 80000-3: Space and time) of the mixture:

γ_{X} = m_{X} / V

pour un constituant $X$ d'un mélange, quotient de la masse $m_{X}$ (ISO 80000-4: Mechanics) du constituant $X$ par le volume $V$ (ISO 80000-3: Space and time) du mélange:

γ_{X} = m_{X} / V

Notes

Decided by the 16^th^ CGPM (1979), both "l" and "L" are allowed for the symbols for the litre.

La 16^e^ CGPM (1979) a décidé que «l» et «L» sont autorisés comme symboles du litre.
