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.
1,000,000 drops of water is rated at only 1.5 Scoville Units. The pungency (or heat factor) of chile peppers is measured in multiples of 100 units. The sweet bell peppers at zero Scoville units to the mighty Naga Jolokia (Ghost Pepper) at over 1,000,000 Scoville units! One part of chile heat per 1,000,000 drops of water is rated at only 1.5 Scoville Units. The substance that makes a chile so hot is called Capsaicin (cap-say-ah-sin).
