What is a chain?

The chain is a unit of length measurement commonly used in surveying and land measurement. It is primarily used in countries that follow the imperial system of measurement, such as the United States and the United Kingdom. One chain is equal to 66 feet or 20.1168 meters. It is further divided into 100 links, with each link measuring 0.66 feet or 7.92 inches.

The chain was historically used for measuring large areas of land, such as farms or estates. Surveyors would use chains to measure distances between points and establish boundaries. The use of chains allowed for more accurate measurements compared to other methods available at the time. Today, the chain is still used in some specialized fields, such as civil engineering and land surveying, although it has been largely replaced by more modern and precise measurement tools like GPS.

What is a US Nautical Mile?

A US nautical mile is a unit of measurement used primarily in navigation and marine activities. It is defined as exactly 1,852 meters or approximately 6,076.12 feet. The term "nautical mile" originated from the need for sailors to measure distances on the Earth's surface while taking into account the curvature of the Earth.

The US nautical mile is based on the international nautical mile, which was established in 1929 by the International Hydrographic Organization (IHO). The IHO defined the nautical mile as one minute of latitude along any meridian. Since the Earth is not a perfect sphere, the length of a nautical mile varies slightly depending on the latitude. However, for practical purposes, the US nautical mile is considered a fixed value.

The US nautical mile is commonly used in marine charts, navigation systems, and aviation. It provides a convenient and standardized way to measure distances at sea, ensuring accurate calculations for ship and aircraft navigation. Additionally, it is used in the calculation of speed over water, known as knots, where one knot is equal to one nautical mile per hour.
