How many Millimeters in a Centimeter?
Millimeters and Centimeters are length measurement units of the metric system. The appropriate abbreviations are respectively mm and cm.
The two units are derived from the base SI unit – the meter. The prefix ‘milli’ means 1/1,000 of, and ‘centi’ – 1/100 of. Therefore, a meter is equal to 1,000 millimeters, or 100 centimeters. So, if 1,000 mm equal 100 cm, then 1 cm is equal to 10 mm.
Difference between Millimeters and Centimeters
The latest official definition of the mm is connected to that of the meter. In 1983, it was established that the fundamental unit is equal to the length of the path that light travels in vacuum in 1/299,792,458 seconds. The mm being 0.001 of a meter, means that a millimeter is the distance travelled by light in vacuum in 1/299,792,458,000 seconds.
Usually, the millimeter is a unit used in engineering and tasks that require great precision, as it measures very small distances.
As already established, the centimeter is 0.01 of a meter and is equal to 10 mm. It is a unit that allows everyday tasks be done precisely and easily. Tailors use centimeters to take measures, for example. Another application is in constructing maps – real-world dimensions are adapted to map scale using cm. Sometimes rainfall levels are also measured in centimeters.
How to convert Millimeters to Centimeters
The conversion from millimeters to centimeters is done with the help of this formula:
mm / 10 = cm.
You can work out an equation, or simply move the decimal point one place to the left.
Mm to cm conversion example
Sample task: convert 50 millimeters to centimeters. Solution:
mm / 10 = cm
50 mm / 10 = 5 cm
50 mm is equal to 5 cm
