The Scoville Heat Scale. The Scoville scale is a measure of the 'hotness' of a chilli pepper or anything derived from chilli peppers, i.e. hot sauce. The scale is actually a measure of the concentration of the chemical compound capsaicin which is the active component that produces the heat sensation for humans.
The more capsaicin present in a pepper, the hotter it will seem. Although the Scoville scale spans from 0 to 16 million, the American Spice Traders Association (ASTA) set the standard for conversion from ppm (parts per million) of capsaicin to Scoville Heat Units as 1:15.
