How many nautical miles are equivalent to one degree?

One degree of latitude is equivalent to 60 nautical miles. This is based on the Earth's geometry, where the circumference of the Earth is divided by 360 degrees, resulting in each degree of latitude representing approximately 60 nautical miles (which is about 1/60th of the circumference).

This measurement is particularly important for navigation because it allows mariners to calculate distances on charts accurately. For every degree of latitude you move north or south, you travel approximately 60 nautical miles. This constant relationship simplifies navigation calculations for sailors as they plot their courses.

Understanding this concept is vital for navigators as they use degrees of latitude to determine their position and the distances they need to travel.
