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

Mile: A Unit of Length

The mile is a unit of length that is equal to 5,280 feet or 1,760 yards. It is based on the older English unit of length that was used before the adoption of the metric system. The mile is also a derived unit in the British imperial and US customary systems of measurement. The symbol for mile is mi or m.

The mile is most commonly used when expressing distances on land or in air travel. The mile is also used for measuring speed, such as miles per hour (mph). The mile is sometimes distinguished from other types of miles, such as the nautical mile or the geographical mile, by using the term statute mile.

Example Conversions of Mile to Other Units

The mile can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of units:

• To convert a mile to feet, multiply by 5,280:

1 mi x 5,280 = 5,280 ft

• To convert a mile to yards, multiply by 1,760:

1 mi x 1,760 = 1,760 yd

• To convert a mile to meters, multiply by 1,609.344:

1 mi x 1,609.344 = 1,609.344 m

• To convert a mile to kilometers, multiply by 1.609344:

1 mi x 1.609344 = 1.609344 km

• To convert a mile to nautical miles, divide by 1.150779:

1 mi / 1.150779 = 0.868976 nmi

• To convert a mile to geographical miles, divide by 0.869:

1 mi / 0.869 = 1.151 mi

• To convert a foot to miles, divide by 5,280:

1 ft / 5,280 = 0.000189 mi

• To convert a yard to miles, divide by 1,760:

1 yd / 1,760 = 0.000568 mi

• To convert a meter to miles, divide by 1,609.344:

1 m / 1,609.344 = 0.000621 mi

• To convert a kilometer to miles, divide by 1.609344:

1 km / 1.609344 = 0.621371 mi

• To convert a nautical mile to miles, multiply by 1.150779:

1 nmi x 1.150779 = 1.150779 mi

• To convert a geographical mile to miles, multiply by 0.869:

1 mi x 0.869 = 0.869 mi
