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 result is a number measured in American Spice Trade Association (ASTA) pungency units, and you can multiply the ASTA pungency units by 15 in order to get the Scoville units. So while the method may have changed, we can still use the Scoville scale to report the heat of a particular pepper.
