What are the nautical measurements?

Nautical miles are used to measure the distance traveled through the water. A nautical mile is slightly longer than a mile on land, equaling 1.1508 land-measured (or statute) miles. The nautical mile is based on the Earth’s longitude and latitude coordinates, with one nautical mile equaling one minute of latitude.

How are nautical miles measured?

A nautical mile is based on the circumference of planet Earth. If you were to cut the Earth in half at the equator, you could pick up one of the halves and look at the equator as a circle. You then divide that circle into 360 degrees, and a degree into 60 minutes. A minute of arc on planet Earth is 1 nautical mile.

Why is nautical miles different?

Such a linear measurement cannot be used at sea, so the nautical mile is based on the length of one minute of arc (or 1/60 of a degree) of a great circle of Earth. Owing to the fact that Earth is not a true sphere, the mile as thus defined varies considerably.

Why are territorial waters 12 miles?

That was linked to the distance of a cannon shot fired from shore. This was considered to be about 3 nautical miles (5.6 kilometers).
