From the volume units for liquid substance shown in conversion table above only fluid ounce, pint, quart, and gallon are still in common use. In 1824 the British imperial gallon was defined to be the volume of water which weighed 10 pounds at 62 [°F] and 30 [in Hg]. The gallon was redefined in 1963 by the WMA to be the volume occupied by 10 pounds of distilled water of density 998.859 \(\left[\frac{\mathrm{kg}}{\mathrm{m}^3}\right]\) weighed in air of density 1.217 \(\left[\frac{\mathrm{kg}}{\mathrm{m}^3}\right]\) against brasss weights of density 8136 \(\left[\frac{\mathrm{kg}}{\mathrm{m}^3}\right]\). By this definition the gallon is equivalent to 4.546092 \(\left[\mathrm{dm}^3\right] = 4.546092 \times 10^{-3} \left[\mathrm{m}^{3}\right]\) based on the new definition of the litre. Although the litre is now official in the UK, it is likely that the pint will be used for some time due to its popularity as a measure of alcoholic beverages (beer).
