Centimeters To Millimeters (Cm to Mm) Conversion Calculator

According to the Centimetre-Gram-Second (CGS) unit system, centimeters to millimeters is one of the most popular and basic units of measurement. Centimeter forms an integral part of the International System of Units (SI) and is denoted by cm. 

What is a Centimeter?

Traditionally 1 cm was measured as the average measurement of an adult’s nail when there were no metric systems in place. Centi means that the unit is a factor of 1/100, and thus, a centimeter is equal to one-hundredth of a meter. The standard small-scale length equals 30 cm. 

If converting Centimeters to Millimeters, the formula is: 
1 cm to mm = 1 X 10 = 10 mm  

For example, if you want to convert 50 cm to mm, simply multiply it by 10.

The answer will be 50 cm = 50 X 10 = 500 mm 

To convert cm to mm, the centimeters to millimeters formula is:

1 cm = 0.01 m 
This also means that
1 m = 100 cm  

Here are some other specifications regarding Centimeters

• • 1 cm = 0.393701 inches
  • 1 cm = 0.0328084 ft
  • 1 cm = 0.01 m
  • 1 cm = 0.0109361 yard
  • 1 cm = 10000 micrometre

• Current Use of Centimeter

You will commonly find the measurements in centimeters on a ruler. Rulers who are 1 m in length have cm calibrations. You can use centimeters as a unit of measurement for hair, clothes, height, etc. normally centimeter is used to measure height, distance, or length. One of the most important uses of a centimeter is to measure rainfall, which is mapped by a rain gauge.

What is Millimeter?

A Millimeter is a prefix to the meter and is the one-thousandth part of a meter. Millimeter generally measures length, and ten millimeters are equivalent to one centimeter. It is denoted by mm, which means 100 millimeters is equal to 100 mm. to measure mm, instead of using a normal scale or ruler, you will have to use a high-quality engineering ruler or a digital caliper. Millimeter is the smallest unit, in any ruler scale, of measurement.  

Here are some specifications regarding millimeters:

• • 1mm = 1000 micros
  • 1 mm = 106 nanometers
  • 1mm =  5/127 or 0.03937 of an inch, or you can say that 1 inch = 25.4 millimeters. 
  • 1 mm = 0.1 cm 
  •  1 mm = one-thousandth of a meter.  

• Current Use of Millimeter

Let us learn some interesting dynamics regarding the millimeter. The human eye can see anything that has a 0.02 to 0.04 mm of circumference. This is usually how thick human hair can be. the frequency of a microwave is 300GHz, which has a wavelength of 1 mm. the millimeter is used to measure the width of the paper, hair strands, the width of CDs, the diameter of a pen nib or pencil lead, the size of tumors, etc. a millimeter is usually used to measure objects that are tiny but visible, and it is used across the world.

Relationship Between Centimeters And Millimeters

It is quite easy to understand the relationship between centimeters and millimeters. As we have studied before:

1 mm = 0.1 cm
And
1 cm = 10 mm. 

Using this centimeters to millimeters formula, you can easily convert any length or circumference from centimeters to millimeters or vice versa. Let us learn how to do that!

How to Convert Centimeters and Millimeters?

We are clear with the formulas of 1 cm being equal to 10 mm. So, if you want to convert cm to mm, simply multiply it by 10. For example:

• • 1 cm = 10 mm
  • 5 cm = 50 mm
  • 10 cm = 100 mm
  • 50 cm = 500 mm
  • 100 cm = 1000 mm

You can use this measurement for several small measurements, for example, measuring a bean, a compact disc, the width of a leaf, or just a plain piece of paper.  

Centimeters to Millimeters Formula & Examples 

The formula to convert cm to mm is:

Millimeter = value of cm x 10 which

The formula to convert mm to cm is:

Centimeter = 0.1 millimeter

Let us consider some examples here:

Example 1

A Banyan Tree Leaf is 2 cm wide. What is the measurement of the leaf in Millimeters?
The width of the leaf = 2 cm
The width of the leaf in millimeter = 2 x 10 = 20 mm

Example 2

A Page has a dimension of width as 200 millimeters. What will be its measurement in centimeters?
The width of a page  = 200 mm
The width of a page in centimeter = 200/10 = 20 cm

Example 3

How will you convert 8 cm, 80 cm, 800 cm, and 8000 cm into mm?
8 cm = 8 x 10 = 80 mm
80 cm = 80 x 10 = 800 mm
800 cm = 800 x 10 = 8000 mm
8000 cm = 8000 x 10 = 80000 mm

Difference Between Millimeters And Centimeters

Let us look at some main points of differences between centimeters and millimeters: 

• Size

Considering the SI metric scale, a centimeter is a little larger as a unit than a millimeter. The millimeter is a very small measuring unit on the scale.

• Symbol

A centimeter is denoted by cm, while a millimeter is denoted by mm.

• Definition

Centi (hundred) and milli (thousand) are both prefixes to the meter, which means that the centimeter is the one-hundredth part of a meter, and a millimeter is the one-thousandth part of a meter.

• Measurement in Comparison to Metre

1 cm is one-hundredth of a meter, whereas 1 mm is one-thousandth of a meter

• Conversion Formula

1 cm = 10 mm, while 1 mm = 0.1 cm

• Use

The centimeter measures the height and length of clothes, furniture, etc., while the millimeter measures smaller configurations like paper, strands of hair, tumor size, etc. besides measuring the distance or length, cm is also used to measure rainfall level. Millimeter, on the other hand, is used to measure the distance and length of extremely small things which are visible. 

Conclusion

Both centimeters and millimeters are extremely important units of measurement of the SI scale and can be used to measure the width, length, or distance of various small or large things. the calculation of cm into mm and vice versa is extremely simple. You can also use the cm to mm calculator online to derive various figures.
