What is a vernier scale?
|Named after the mathematician who invented it, Frenchman Pierre Vernier (not pictured), the vernier scale is a scale used to determine more accurate measurements (be they distances or angles).|
|It determines measurements in between those marked on “primary scales”.|
|For angles, the “primary scale” is in degrees, whilst the vernier scale measures in “minutes”.|
|One minute is equal to 1/60th of a single degree.|
