Scoville scale Scoville Heat Units can be made by multiplying ppm H by a factor of 15" (modified to a factor of 16 by others). Another source using subjective assessment stated: "Conventional methods used in determining the level of pungency or capsaicin concentration are using a panel of tasters (Scoville Organoleptic test method). ... Pepper pungency is measured in Scoville Heat Units (SHU). This measurement is the highest dilution of a chile pepper extract at which heat can be detected by a taste panel (Bosland et al., 2007)." Since Scoville ratings are defined per unit of dry mass, comparison of ratings between
Sigma heat Sigma heat Sigma heat, denoted formula_1, is a measure of the specific energy of humid air. It is used in the field of mining engineering for calculations relating to the temperature regulation of mine air. Sigma heat is sometimes called "total heat", although total heat may instead mean enthalpy. Sigma heat is the energy which would be extracted from a unit mass of humid air if it were cooled to a certain reference temperature under constant pressure while simultaneously removing any condensation formed during the process. Because sigma heat assumes that condensation will be removed, any energy which would be
