  8. A measure of the alcohol content of liquor. Originally in Britain 100 proof was defined as 57,1% by volume (not used anymore). In the US 100 proof means that the alcohol content is 50% of the total volume of the liquid and thus absolute alcohol would be 200 proof.

Fahrenheit being of specific gravity 0.7939 referred to water at its maximum density as unity. Proof spirit has at 15.556 deg. Celsius, a specific gravity of 0.93353, 100 parts by volume of the same consisting of 50 parts of absolute alcohol and 53.71 parts of water, the apparent excess of water being due to contraction of the liquids on mixture.
