Wilbur Scoville Wilbur Scoville Wilbur Lincoln Scoville (January 22, 1865 – March 10, 1942) was an American pharmacist best known for his creation of the "Scoville Organoleptic Test", now standardized as the Scoville scale. He devised the test and scale in 1912 while working at the Parke-Davis pharmaceutical company to measure pungency, "spiciness" or "heat", of various chili peppers.

Vernier scale between two points. Such an arrangement can go to higher resolution by using higher scale ratios, known as the vernier constant. A vernier may be used on circular or straight scales where a simple linear mechanism is adequate. Examples are calipers and micrometers to measure to fine tolerances, on sextants for navigation, on theodolites in surveying, and generally on scientific instruments. The Vernier principle of interpolation is also used for electronic displacement sensors such as absolute encoders to measure linear or rotational movement, as part of an electronic measuring system. Calipers without a vernier scale originated in ancient China as
