The Difference between Cm and Mm
Why we use Measuring Units?
Measurement is significant in life. When we buy something we weigh it or measure it by using different measuring units. Both millimeters and centimeters are terms used to measure quantities. There are certain point of differences between millimeters and centimeters.
See the table:
Centimeter |
Millimeter |
Centimeters are abbreviated as cm.
|
Millimeters are symbolized as mm
|
Cm is used for measuring the height of a person, the length of
any object and distance. |
Millimeters can’t measure the height of a person. Mm can measure
the thickness of the objects; the diameter of cables, barrels etc, the
distances between the two points, the depth of rivers & lakes, oceans and the width of a paper sheet, and
for measuring the size of a medicine ETC |
Cm can be measured by a ruler because Cm
doesn’t come in a rounded and decimal value. |
The smallest measuring line in the ruler is
known as millimeters oftenly used in geometry measures. |
The unit system for centimeter is Metric. |
The unit system for Millimeters is System International derived
unit.
|
Cm is one hundredth of a meter. SO, there are 100 centimeters
in a meter
|
Mm is one thousandth of a meter. So, there are 1000 millimeters in a meter. |
Cm is bigger to Mm. One cm is equal
to 10 mm |
Mm is smaller to Cm. One mm is equal to 0.1 cm |
Let’s understand by taking some Examples
Example of Millimeter (Mm)
- Let’s take an example of most rainy place in America, ‘Hawaiian island’ where meteorologists recorded 5,080 mm rain & drizzle in latest years.
- Generally, A pencil point is 1mm.
- If we look at average Human hair volume , its thickness ranges from 0.016-0.05 mm
Example of Centimeter (Cm)
- The average human brain is 15 cm long.
- US passport photo size is 5.0 × 5.0 cm
- Standard international paper A4 size is 21.0 x 29.7 cm.
It’s clear now that Cm & Mm although both are measuring units rather hold marked differences.
