There are three norths commonly used in Great
Britain:
• Grid North: the direction of a grid line which is
parallel to the central meridian on the National
Grid.
• True North: the direction of a meridian of
longitude which converges on the North Pole.
• Magnetic North: the direction indicated by a
magnetic compass. Magnetic North moves slowly
with a variable rate and currently is West of Grid
North in Great Britain.
