Magnetic declination calculator

A magnetic declination is the angle between the the horizontal plane and magnetic north (direction your compass needle points) and true north (actual direction along a meridian towards the North Pole). Magnetic declination varies both from place to place as well as over time. The magnetic declination varies depending on where you are located on the Earth’s surface, and varies over time.
