Please provide values below to convert millimeter [mm] to centimeter [cm], or vice versa.
Definition: A millimeter (symbol: mm) is a unit of length in the International System of Units (SI). It is defined in terms of the meter, as 1/1000 of a meter, or the distance traveled by light in 1/299 792 458 000 of a second.
History/origin: The milli- prefix is one of many metric prefixes. It indicates one thousandth of the base unit, in this case the meter. The definition of the meter has changed over time, the current definition being based on the distance traveled by the speed of light in a given amount of time. The relationship between the meter and the millimeter is constant however. Prior to this definition, the meter was based on the length of a prototype meter bar. In 2019, the meter has been re-defined based on the changes made to the definition of a second.
Definition: A centimeter (symbol: cm) is a unit of length in the International System of Units (SI), the current form of the metric system. It is defined as 1/100 meters.
History/origin: A centimeter is based on the SI unit meter, and as the prefix "centi" indicates, is equal to one hundredth of a meter. Metric prefixes range from factors of 10-18 to 1018 based on a decimal system, with the base (in this case the meter) having no prefix and having a factor of 1. Learning some of the more commonly used metric prefixes, such as kilo-, mega-, giga-, tera-, centi-, milli-, micro-, and nano-, can be helpful for quickly navigating metric units.
Current use: The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in centimeters outside of countries like the United States.
1 mm = 0.1 cm1 cm = 10 mm
Example: convert 15 mm to cm:
Centimeters and Millimeters are quite basic units and I hope all of you might be familiar with them. Therefore, converting centimeters to millimeters could be a bit easier compared to other metric or non-metric conversions. For some, millimeters could be a bit perplexing, but don’t you worry! We have got you covered. We will go through the concept of a millimeter and its current use thoroughly. Besides, we have also covered a few examples along with the conversion process. It will help you understand the notion of unit conversions in a better way. However, before delving into that, it’s important you understand the units well. So, let us first start with the definition of centimeters.

What is a Centimeter?
A centimeter is a unit of length in the metric system. It is equivalent to one-hundredth of a meter, centi being the SI prefix for a factor of 1/100. In the current deprecated CGS (centimeter-gram-second) system of units, the centimeter was considered the base unit of length.
Although SI prefixes for factors of 103 such as milli and kilo are often used by technicians for measuring various physical quantities.
A centimeter is roughly equivalent to the width of the fingernail of an average adult person.
Current Use of Centimeter
From the definition, it’s clear that the centimeter usually measures the length or the distance. Apart from that, it is also used to report the level of rainfall, which is mapped by a rain gauge.
In the CGS system, a centimeter mainly measures the capacitance, where 1 cm of capacitance equals 1.113×10−12 farads.
What is Millimeter?
A Millimeter is a unit used to measure the length in the metric system. It’s a prefix to the meter and one-thousandth part of a meter. This implies that a meter is equivalent to one thousand millimeters. While ten millimeters equals one centimeter.
The millimeter is abbreviated as mm. Therefore, you can represent 7 millimeters as 7 mm, 8 millimeters as 8 mm, 100 millimeters as 100 mm, and more.
One millimeter is equivalent to 1000 microns or micrometers or 106 nanometers. Precisely, one mm equates to exactly 5/127 of an inch or about 0.03937 of an inch, whereas an inch is equal to exactly 25.4 millimeters.
Unlike other units such as inches and centimeters, you can’t measure objects in millimeters with a ruler or tape. Rather you will require a high-quality engineering ruler of a digital caliper.
Current Use of Millimeter
A Millimeter measures the length and distance of tiny objects that are visible. Comparing it with the real world, a millimeter is roughly equivalent to the wire's size in a standard paper clip. Moreover, the unit is used worldwide.
Relationship between Centimeters and Millimeters
Metric conversions are easy to understand, and so is their relationship with different units of measurement.
For instance, one mm is equivalent to 0.1 cm. However, one cm is equal to 10 mm.
Expressing it in the form of an equation, we will get-
1 cm = 10 mm, and
1 mm = 0.1 cm
Wasn't that too easy?
Now that you are clear about that, you can take a step towards the conversion of cm into mm.
How to Convert Centimeters and Millimeters?
Just like the relationship, the conversion process is pretty simple. All you have to do is multiply the value of cm by 10.
If yes, well done! In case you don't get it, let us have a look at the formula and examples.
Formula & Examples
The formula to convert cm to mm can be expressed as follows:
Millimeter = value of cm x 10
Simply input the values in the above equation. Voila! You will be done.
Example 1: Convert 85 cm to mm
Putting the value of cm in the above equation, we will get-
Millimeter = 85 x 10 = 850 millimeter.
Therefore, 85 centimeters is equal to 850 millimeters.
Example 2: Convert 90 cm to mm
Following the same process as above, we will get-
Millimeter = 90 x 10 = 900 millimeters.
Hence, 90 centimeters is equal to 900 millimeters.
Now, let us have a look at the centimeter to millimeter conversion chart. It will help you escape from converting units up to 100 digits.

Frequently Asked Questions (FAQs)
It’s pretty easy. Simply multiply the value of cm by 10. The answer you will obtain will be the converted value.
For example- Convert 4.5 cm to mm
Sol: Kilometer = value of cm x 10 = 4.5 x 10 = 45 mm.
The formula for converting centimeters to Millimeters is as follows:
Millimeters = value of cm x 10
There are 10 millimeters in 1 centimeter.
There is 0.1 centimeter in 1 millimeter.
Centimeter usually measures the length or the distance. Apart from that, it is also used to report the level of rainfall, which is mapped by a rain gauge. On the other hand, a millimeter measures the length and distance of tiny objects that are visible.
