History

The Old English word "fot" is where the word "foot" (meaning "terminal part of the leg of a vertebrate animal") came from.

Historically, the "foot" was a part of many regional systems of units, such as the Greek, Roman, Chinese, French, and English systems. The first recorded standard foot measure comes from Sumer, where a definition is given in a statue of Gudea of Lagash from around 2575 BC.

The millimeter is represented by the symbol "mm." 

Description

Millimeter is an SI (International System of Units) unit of length. It is usually the smallest measure in rulers of the metric system.The word "milli" is derived from the Latin word mille, which means one thousandth. Therefore, a meter is equivalent to a thousand times a millimeter.

The international definition of meter which is the SI base unit of length, is the length of path that light takes in the vacuum over a period of 1/299 792 458 of a second. Thus, 1 millimeter is equivalent to 1/1000 meter. That implies that a millimeter is the distance that light travels in the vacuum in 1/299792458000 seconds.

Following that, there are 10 millimeters in a centimeter and 100 millimeters in a decimeter. In the other direction, a millimeter is equivalent to 1/10 centimeters. A millimeter is also equivalent to 1000 micrometers.

Interestingly the smallest dimension human eyes can detect is about 0.02 to 0.04 mm. This is about the thickness of human hair!

History

The term millimeter was first used in the late 1700s. It was introduced during the development and adoption of the metric system of weights and measures in France in 1795.

The first recorded use of the millimeter was in the Journal of Natural Philosophy in 1797, according to OED (Oxford English Dictionary).
