First definition of "Jiffy" -equal to the time it takes light to travel one centimeter
The earliest technical usage for jiffy was defined by Gilbert Newton Lewis (1875–1946). He proposed a unit of time called the "jiffy" which was equal to the time it takes light to travel one centimeter (approximately 33.3564 picoseconds).[2] It has since been redefined for different measurements depending on the field of study.[3] Don't forget to check out our Kickstarter Campaign!
