## Nautical Mile: A Unit of Length

A nautical mile is a unit of length that is used in air, marine, and space navigation, and for the definition of territorial waters. It is based on the Earth’s longitude and latitude coordinates, and is equal to one minute of arc along a meridian. In this article, we will explore the definition, history, uses, and conversions of the nautical mile.

## How to Convert Nautical Mile

The nautical mile can be converted to other units of length using simple multiplication or division by a conversion factor. Here are some common conversion factors:

Unit
Conversion Factor
Metre 1,852
Foot 6,076
Statute mile 1.151
Kilometre 1.852
Yard 2,025

For example, to convert 10 nautical miles to kilometres, we multiply by 1.852:

10 NM × 1.852 = 18.52 km

To convert 50 kilometres to nautical miles, we divide by 1.852:

50 km ÷ 1.852 = 27 NM

The international nautical mile was defined as exactly 1,852 meters in 1929.

## Chain: A Unit of Length

The chain is a unit of length that is equal to 66 feet or 22 yards or 4 rods or 100 links. It is part of the US customary and imperial measurement systems. It is used for measuring land, especially in surveying and mapping. The symbol for chain is ch. There are 10 chains in a furlong, and 80 chains in one statute mile. An acre is the area of 10 square chains. The unit is named after the chain, a measuring device that was invented by Edmund Gunter, a clergyman and mathematician, in the 17th century. The chain is also sometimes called a Gunter’s chain, a surveyor’s chain or a land chain. In this article, we will explore the definition, history, usage and conversion of the chain as a unit of length.

## How to Convert

The chain can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert chains to other units of length in the US customary system, the imperial system and the SI system:

• To convert chains to feet, multiply by 66. For example, 10 ch = 10 × 66 = 660 ft.
• To convert chains to yards, multiply by 22. For example, 10 ch = 10 × 22 = 220 yd.
• To convert chains to miles, divide by 80. For example, 10 ch = 10 / 80 = 0.125 mi.
• To convert chains to centimeters, multiply by 2011.68. For example, one ch = one × 2011.68 = 2011.68 cm.
• To convert chains to meters, multiply by 20.1168. For example, one ch = one × 20.1168 = 20.1168 m.
• To convert chains to kilometers, divide by 49.7097. For example, 10 ch = 10 / 49.7097 = 0.2012 km.
