# Often asked: Why Is Nautical Miles Used In Aviation?

## Why don’t we use nautical miles on land?

Because, just like in sailing on the open ocean, when you are traveling a long distance you want to use a unit of length that is directly related to latitude and longitude. The nautical mile is one minute of latitude. Knowing your latitude you also know the factor to determine what one minute of longitude is.

## Do airlines use nautical miles?

A nautical mile measures the same as an air mile, 6,076 feet, or 2,025.3 yards. Though they are the same measurement, nautical miles are used for aquatic travel, and air miles are used only for air travel. A nautical mile can also be referred to a as sea mile.

## Why do we use knots instead of mph?

In this method, knots were tied at uniform intervals in a length of rope and then one end of the rope, with a pie-slice-shape piece of wood (or “chip”) attached to it, was tossed behind the ship. A knot came to mean one nautical mile per hour. Therefore, a ship traveling at 15 knots could go 15 nautical miles per hour.

## Why is it called a nautical mile?

Historically, it was defined as the meridian arc length corresponding to one minute (160 of a degree) of latitude. Today the international nautical mile is defined as exactly 1852 metres (6076 ft; 1.151 mi). The derived unit of speed is the knot, one nautical mile per hour.

## What is faster a knot or mph?
