## How long is a jiffy?

Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds. It has also more informally been defined as “one light-foot”, which is equal to approximately one nanosecond.
