A carpenters' ruler with centimetre divisions

A centimetre (American spelling: centimeter, symbol cm) is a unit of length in the metric system, equal to one hundredth of a metre, which is the current SI base unit of length.

Phonology North American English regional phonology In many ways compared to English English, North American English is conservative in its Phonology. Length is the long Dimension of any object The length of a thing is the distance between its ends its linear extent as measured from end to end The metric system is a decimalised system of measurement. It exists in several variations with different choices of base units, though the choice of base units does The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International The International System of Units (SI defines seven dimensionally independent SI base units. Centi is the SI prefix for a factor of 10 ^{− 2}. An SI prefix (also known as a metric prefix) is a name or associated symbol that precedes a unit of measure (or its symbol to form a Decimal multiple or ^[1] Hence a centimetre can be written as 10×10 ^{− 3} m (engineering notation) or 1 E-2 m (scientific E notation) — meaning 10 × 1 mm or 1 m / 100 respectively. Engineering notation is a version of Scientific notation in which the power of ten must be a multiple of three (i Scientific notation, also sometimes known as standard form or as exponential notation, is a way of writing numbers that accommodates values too large or small to be The Millimetre ( American spelling: millimeter, symbol mm) is a unit of Length in the Metric system, equal to The centimetre is the base unit of length in the now deprecated centimetre-gram-second system of units. The centimetre-gram-second system ( CGS) is a system of physical units.

Though for many physical quantities, SI prefixes for factors of 10³ - like milli and kilo - are often preferred by technicians, the centimetre remains a practical unit of length for many everyday measurements. An SI prefix (also known as a metric prefix) is a name or associated symbol that precedes a unit of measure (or its symbol to form a Decimal multiple or A centimetre is approximately the width of the fingernail of an adult person.

Equivalence to other units of length

1 centimetre is equal to:

• 0. 01 metres, which can be represented by 1.00 E-2 m (1 metre is equal to 100 centimeters)
• about 0. To help compare different Orders of magnitude this page lists lengths between 10&minus2 m and 10&minus1 m (1 cm and 10 cm 393700787401575 inches (1 inch is equal to 2. Inches redirects here To see the Les Savy Fav album see Inches. 54 centimetres exactly) ^[2]

1 cubic centimetre is equal to 1 millilitre, under the current SI system of units. The litre or liter (see spelling differences) is a unit of Volume.

Uses of centimetre

In addition to its use in the measurement of length, the centimeter is used:

• sometimes, to report the level of rainfall as measured by a rain gauge ^[3]
• in the CGS system, the centimetre is used to measure capacitance, where 1 cm of capacitance = 1. Length is the long Dimension of any object The length of a thing is the distance between its ends its linear extent as measured from end to end A rain gauge (also known as a udometer or a pluviometer or a cup) is a type of instrument used by meteorologists and Hydrologists Capacitance is a measure of the amount of Electric charge stored (or separated for a given Electric potential. 113×10 ^{− 12} Farad ^[4]
• in Canadian maps, centimetres are used to make conversions from map scale to real world scale (kilometers)

Unicode symbols

For the purposes of compatibility with Chinese, Japanese and Korean (CJK) characters, Unicode has symbols for: ^[5]

• centimetre (㎝) - code 339D
• square centimetre (㎠) - code 33A0
• cubic centimetre (㎤) - code 33A4

They are useful only with East Asian fixed-width CJK fonts, because they are equal in size to one Chinese character.
