Millimeters to Kilometers (mm to km) Conversion Online

How many times do you use measurements in your everyday life? Quite often than you think. Whether you’re getting your clothes stitched or getting a new oakwood cupboard for your room. Conversion is always helpful in these matters. Converting units from MM to KM is not an impossible task. However, the relationship between them is simple and familiar to the one you have been studying in school all along. 

Let’s dive right into the details of the mm to km conversion.

What is Millimeter?

A millimetre is a measurement unit used to measure the length of small scales and small visible objects. It is a one-thousandth part of a metre which makes up a millimetre. Therefore, we can say that a metre has one thousand millimetres. Further, there are 10 millilitres equivalent to one centimetre.

History of Millimeter

The abbreviation of Millimetre is mm. You can write 20 millimetres as 20 mm and others. One mm is equivalent to 1000 Micrometers/Microns or 1,000,000 Nanometers. Also, an inch is equivalent to 25.4 millimetres. Thus, a millimetre is equal to 5/127 approximately, which is 0.03937 of an inch. 

Further, for Centimetres and Inches, you cannot use a tape or ruler to measure the length of any small object in mm. Therefore, you need a very high-quality digital calliper. 

Current Use of Millimeter

Millimetres help in marking the distance or the length of the map. In other words, mm is used to map the distance on a small but visible scale. In the real world, a millimetre is equivalent to the size of the wire in a paper clip. The millimetre is used across the globe.

What is Kilometer?

A kilometre is a distance travelled by light in a vacuum in 1/299,792,458 seconds. In 1 km, there are 1000 metres. Or we can say that a thousand multiples of the SI-based unit of length metre is Kilometre.

The prefix of the kilogramme, kilo, is a prefix of 103 International System of Units. It is abbreviated as km. Thus, we can write 70 kilometres as 70 km.

History of Kilometer

A kilometre is made up of two Greek words. The first Greek word ‘Kilo’, means 1000,and the other word ‘Meter’ a unit that measures the amount of gas, water, electricity, voltage, etc amount. 

The km unit is used for mapping distances between one location and another across the globe. Only the UK and the US use miles over kilometres.

Current Use of Kilometer

A kilometre is used worldwide, except for the UK and the US. It is used to measure the distance or demonstrate the distance between one geographic location and another. 

Relationship Between Millimeters and Kilometers

To understand the relationship between mm and km, you must understand the relationship behind both the measuring units. 

The relation can be represented as follows:

1 mm = 10^-6 Km, and

1 Km = 10^6 mm

Now, you know the value of kilometers in 1 mm and vice-versa. Converting one unit into another is possible.

How to Convert Millimeters to Kilometers?

Converting mm to km is quite easy. You just have to multiply the value of mm by 10^-6. The equation will revert if you want to get the values in km.

Let’s move further and see how the mathematical expression helps in making the conversion of m to km easy, along with a few examples. 

Formula and Examples of mm to km Conversion

You can use the following formula to convert mm to km:

Kilometer = value of mm x 10^-6

Here are some examples that will help you understand and solve the queries regarding the conversion of mm to km.

Example 1: Convert 6 mm to km.

Solution 1: Putting the value of mm in the conversion formula of mm to km, we will get-

Kilometre = value of mm x 10^-6

Kilometre = 6 x 10^-6 = 0.000006 Kilometre.

Therefore, 6 millimetres is equal to 0.000006 kilometres. 

Example 2: Convert 5000 mm to km.

Solution 2: We will place the values in the conversion formula of mm to km.

Kilometer = value of mm x 10^-6

Kilometer = 5000 x 10^-6 = 0.005 kilometer.

Therefore, 5000 millimeters is equal to 0.005 kilometers. 

Example 3: Convert 9500 mm to km

Solution 3: We will place the values in the conversion formula of mm to km.

Kilometre = value of mm x 10^-6

Kilometre = 9500 x 10^-6 = 0.095 kilometre.

Therefore, 9500 millimetres is equal to 0.095 kilometres.

Difference between Millimeters and Kilometers

Until now you might have got an idea about the biggest difference between the units. While a Millimeter is quite small in size, a Kilometer is a million times larger than an mm. Besides, their differences lie on various other grounds as well. They are as follows: 

FAQ’s about MM to KM

You can calculate the value of the millimetre by 10^-6. However, the equation will revert the values in Kilometers.  

For example: Convert 1000000 mm to km

Solution: Kilometer = value of mm x 0.000001 

1000000 x 0.000001 = 1 KM.

You can convert Millimeters to Kilometers as follows:

Kilometres = value of mm x 10^-6

There are 10^-6 kilometres in 1 Millimeter

1 million Millimeters (1,000,000 mm) are there in 1 Kilometer.

Millimeters are used for measuring the diameter or length of very small yet visible objects. However, kilometres are used for measuring or estimating the distance between one another geographical locations.
