Did you know? When is a second not a second?


Most of us know that a second is a unit of time. There are sixty seconds in a minute and sixty minutes in a hour.

However, the term second is also a term used in measuring angles. Angles are usually measured in degrees. However, like most measurements, we can get very precise. Degrees are divided into 60 minutes (1 degree = 60 minutes) and minutes are further divided into seconds (1 minute = 60 seconds).

In mapping on a global scale, precise measurement is key. A difference of 1 second of longitude or latitude is over 100 feet (depending on terrain).
