Every measurable physical quantity has its relevant metric unit to convey the proportion of its measurement. One often sees the term ‘mm’ on measuring tapes or product descriptions. The acronym ‘mm’ and ‘m’ stands for millimeter to meter, a metric unit for measuring lengths. However, understanding units and the ability to convert them helps in their daily lives and is, in reality, not so complicated when one understands the basics. This article will discuss different facets of the units of meter and millimeter in detail and then further explain the conversion of a millimeter to meter (mm to m). With a detailed guide on mm to meter conversion, everyone can become a pro in unit conversion from this point onwards.

Define Millimeter

Millimeter is a metric unit of length used to measure small objects, like the diameter of a wire. The symbol for millimeters is mm. Measuring in units of meters or kilometers would seem absurd to express the lengths of such minute objects. One can compare it with a meter to gauge how long an ‘mm’ is.

A millimeter is equivalent to the 1000th part of a meter (m). To convert mm to m is simple. One can also estimate the length of a millimeter by comparing it to a centimeter. A millimeter is equivalent to one-tenth part of a centimeter.

While measuring very minute objects, one uses smaller units than a millimeter, like a micrometer or a nanometer. One millimeter consists of 1000000 nanometers and 1000 micrometers. This article discusses mm to m conversion and vice versa.

  • Application of Millimeters in Daily Lives

One uses the unit of a millimeter for things considered small for units like meters or kilometers. Some of the examples of objects often measured in millimeters are:

    • The thickness of the paper
    • The diameter of a sharp pencil nib
    • A pea

One can convert mm to the meter if one is more used to the unit of meter in their day-to-day activities.

Define Meter

According to the International System of Units, a meter is the base unit of the length. It is expressed as ‘m’. One meter consists of 1000 millimeters. It is the most widely used unit of length in our daily lives.

However, a larger unit of a kilometer is the preferred unit of measurement for lengthy dimensions like the distance between two places. One kilometer consists of 1000 meters.

Again, a millimeter or centimeter is the preferred unit for smaller objects. One meter consists of 100 centimeters and 1000 millimeters. In this blog, we will discuss mm to meter conversion.

  • Applications of Meter in Everyday Lives

On most occasions, one uses meters to express the length of the following objects.

    • Length of a table
    • Dimensions of a field
    • Dimensions of a swimming pool
    • Doors

These objects are too long to be measured in smaller units like centimeters or millimeters. But of course, one can convert the units of measurement according to their convenience. This article will teach how to convert mm into m in a little while.

Method To Convert Millimeters To Meters (mm to m)

Everyone’s memory from school might make the conversion of units an off-putting experience. But, if one understands the basic principle that one meter consists of 1000 millimeters, it will become a cakewalk to convert 1 mm to m.

One millimeter consists of one-thousandth part of a meter, which implies that one has to divide the quantity in millimeters by 1000 to find its equivalent in meters. Isn’t it easy to convert mm to meters?

Millimeters to Meters (mm to m) Conversion Formula : One-Step Solution

There is a simple mm to m formula for conversion.

Length in millimeters/1000 = Length in meters.

It is the only formula one must remember while converting mm to a meter. So, for instance, if someone wants to convert 40 mm into a meter, they must divide 40 mm by 1000, i.e., 40 mm / 1000= 0.004 m.

Here’s a detailed mm to meter conversion table in ascending order to elucidate the process better.

Millimeters (mm)

Meters (m)

0.01 mm =

0.00001 m

0.1 mm =

0.0001 m

1 mm =

0.001 m

2 mm =

0.002 m

3 mm = 

0.003 m

4 mm =

0.004 m

5 mm =

0.005 m

10 mm =

0.01 m

20 mm =

0.02 m

40 mm =

0.04 m

60 mm =

0.06 m

90 mm =

0.09 m

100 mm =

0.1 m

300 mm =

0.3 m

500 mm =

0.5 m

600 mm =

0.6 m

700 mm =

0.7 m

800 mm =

0.8 m

900 mm =

0.9 m

1000 mm =

1 m

As long as one remembers the mm to meter or mm to m formula for conversion, one will have no problem proceeding.

Applications of Millimeters to Meters Conversion In Daily Lives

As already discussed, divide the measurement of length in millimeters by 1000 to convert mm into m. Sometimes some lengths are provided in millimeters, but one can better understand them in meters. Hence, they often choose to convert such lengths from millimeters to meters.

For example, people often come across the length of wood planks for doors in millimeters, but it is more convenient when expressed in meters. Similarly, the length of curtains is more appropriate to be measured in meters.

Hence, if the length is in mm, people convert mm to meters for convenience. The trick to knowing which unit is more suitable for an object depends on eliminating as many decimals from the number as possible. If one gets the length of an object in meters, but it has too many decimals, it would better suit their purpose to convert it into mm or centimeters.

Conversely, if the given length of an object is in millimeters but has too many decimals, one might get a better number by converting mm to m.

Comparison Between Millimeters And Meters (mm to m)

Let us compare some of the tenets of both the units, meter and millimeter, to understand them better.

Basis of Comparison

Millimeters (mm)

Meters (m)


Millimeter is a metric unit of length for small objects. It is equivalent to one-thousandth part of a meter.

  A meter is the SI unit of measuring length. It is equivalent to 1000 mm.


We write it as mm.

  We express it as m.


1 mm = 0.001 m

1 m = 1000 mm


 A millimeter is a thousand times smaller than an object, 1 m in length. 

A meter is 1000 times larger than an object, 1 mm in length.


We use it to measure the length of minute objects, like the thickness of a wire. 

We use it for standard-sized objects like a table or a door.

Define Square Millimeter (mm²)

A square millimeter measures the area of a quadrilateral like a square or a rectangle with sides expressed in millimeters. One can write it as mm². 1 square millimeter is the area of a square which is 1 millimeter on each side. This unit is used to measure the area of surfaces which are small in size. 

Define Cubic Millimeter (mm³)

A cubic millimeter calculates the volume of an object, like a cuboid. Of course, the edges of the structure have to be in millimeters to determine the volume in cubic millimeters. One can write it as mm³. 1 cubic millimeter is the volume of a cube that has edges, 1mm in length. 

Wrapping Up

Understanding units and converting one form to another can be a little intimidating, but remembering the formulas of conversion goes a long way to ease the process.  Although many things in mathematics learned at school might not be of much use, the conversion of physical quantities from one unit to the other is something one often find handy. For instance, one might need to convert the length of a curtain from centimeters into meters to understand its size in terms of the window. To keep things simple, this article has focused on only one aspect of conversion, mm to meter, and vice versa. We hope this article will enable everyone to undertake mm to m conversions without trouble.
