## How to convert

1 chain (ch) = 20116.8 millimeter (mm). Chain (ch) is a unit of Length used in Standard system. Millimeter (mm) is a unit of Length used in Metric system.

## 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.

• ## Millimeter: A Unit of Length

A millimeter is a unit of length in the metric system, which is based on the International System of Units (SI). It is defined as one thousandth of a meter, which is the SI base unit of length. One millimeter can be written as 1 mm or 0.001 m.

## How to convert millimeter to other units of length

To convert millimeter to other units of length, we need to use conversion factors that relate the millimeter to the desired unit. For example, to convert millimeter to centimeter, we need to know that 1 cm = 10 mm, so we can divide the number of millimeters by 10 to get the number of centimeters. Similarly, to convert millimeter to inch, we need to know that 1 in = 25.4 mm, so we can divide the number of millimeters by 25.4 to get the number of inches.

Here are some common conversion factors for millimeter and other units of length in the US standard system and the SI system:

• 1 mm = 0.1 cm
• 1 mm = 0.03937 in
• 1 mm = 0.001 m
• 1 mm = 0.000001 km
• 1 mm = 0.00000062137 mi
• 1 mm = 0.00000053996 nmi
Millimeters also can be marked as millimetres.
