Mathematics has a predefined set of measurement units to measure the length, distance, or volume of any object. These measurement units simplify the process to know how much distance is there between home and the railway station? Or how much is the length of a cloth? Multiple measurement units are used to calculate the length, distance. For example, km, m, mm, etc. With the measurement units, we ward off the ambiguity or difference in the calculation.

In this article, we will focus on m and mm and how to convert m to mm. So, keep on reading to learn about m, mm, and the conversion.

What is Meter (m)?

A meter is a SI unit used to measure length and distance. The notation of Metre (m) is often defined as the distance covered by light in a period of 1/299 729 458 of a second. The meter unit has been revised my times in the past. Currently, the definition of meter has been adopted from the 1983 definition with some slight tweaks and modifications.

All around the world, the meter is used to measure length, height, width, and distance, etc. However, in the US, in place of meters, measurement units such as inches, yards, and miles are used.

What is a Millimeter (mm)?

A millimeter (mm) is a SI unit to measure length. The base unit of mm is often defined in terms of m, like from m to mm. The conversion of 1m to mm is quite an easy task. As per mathematical rule, mm is equal to 11000 m.

Also, mm can be defined as the distance covered by light in a 1/299 729 458 000 of a second.

What Does it Mean by Metre to Millimeter Conversion?

The conversion of m to mm simply means translating the meter measurement into the millimeter unit. As discussed above, both of the units are base units of international standard units (SI) for length and distance. The notation of Metre is m and millimeter is mm. The m to mm conversion chart helps to convert the m into mm.

The relationship between the m and mm is that 1m equals mm of 0.001.

Or we can say that,

1 mm = 1000 m

The conversion of m to mm shows that Metre is 1000 times bigger than a millimeter.

How to Convert m to mm?

The process to convert m to mm is a very simple task. All you have to do is multiply 1000 with the Metre measurement to get the measurement in millimeters.

For example, the conversion of 8m into mm is as follows:

1m = 1000 mm

Therefore, 8m = 8×1000

=8000 mm.

Hence, the 8 Metre to mm conversion is 8000 mm.

What is the m to mm Conversion Calculator?

Meter to millimeter conversion calculator is an online tool that helps you to convert m to mm in seconds. By using this tool, you are no longer required to do the tedious task of multiplication or division for conversion both ways, especially when the numbers are large or you’re dealing with a bigger project. The conversion calculator shows the conversion value on the screen in a second without any error.

How to Use the m to mm Conversion Calculator?

It is very easy to use the conversion calculator. You’ve to follow only three simple steps to get the results in a jiffy, which are as follows:

Step 1: First off, after opening the calculator you have to enter the meter measurement in the given field.

Step 2: After entering the meter unit, Click on “CONVERT” to convert m to mm.

Step 3: After processing, the converted value into mm will be shown on the screen in the output box.

Solved Example

Question: How many millimeters are there in 0.845 meters?

  1. 84.5 mm

  2. 845 mm

  3. 8450 mm

  4. 8.450 mm

Answer is an option (b)

Explanation: 1m = 1000 mm

So, 0.845 m = 0.845 × 1000 = 845 mm

Therefore, there are 845 millimeters in 0.845 meters.


Metre and millimeters are basic SI units to measure length, height, width, and distance. One meter is equal to 1000 millimeters, which states that one unit of meter is 1000 times the unit of a millimeter. You can also use the conversion calculator to convert 1m to mm and so on.

FAQs on Meter to Millimeter

1. What is the relationship between meter and millimeter?

Metre and millimeters are base units of measurement for length, distance, width, and height. Both units play a very important role in measuring the dimensions. However, the question arises if there is any relationship between both of them. 

There exists a strong relationship between both the units. One unit of meter is equal to thousand units of a millimeter.

Mathematically, it can be written as:

1m = 1000 mm

Or, we can say that, 1mm = 0.001 m

Therefore, we can say that if you’ve to convert 1m to mm, then you have to multiply the 1m with 1000 to get the converted results of 1000 mm.

2. Is the meter a greater or bigger unit than a millimeter?

Metre is a greater unit than a millimeter. The conversion chart of the meter into millimeters shows that a one-meter unit equals thousand-millimeter units. This implies that the accumulation of thousand units of millimeters makes up to a meter.

It can be written as follows:

1m = 1000 mm

Or, 1mm = 0.001 m

From the conversion equation, it is clear that one unit of a millimeter is a very small measure in terms of meters. 

Hence, we can say that a millimeter is a smaller unit than a meter.
