How to convert meters to centimeters, millimeters, kilometers

How to convert meters to centimeters, kilometers, millimeters.

Many users of the Internet wonder – how to translate meters into centimeters? It would seem that this is a topic of the elementary school curriculum. But if you are working with large arrays of numeric data in engineering applications, the brain is so loaded, sometimes even the simplest formula is forgotten.

So, now I’m going to talk about ways to convert m to cm (and not only) manually or using online calculators.

What is a centimeter?

I won’t go into historical points, I’ll just say: the word is of French origin – “centimètre” and consists of two parts:

There are also Greek and Latin versions, but we shouldn’t go into it now, because we are more interested in the practical part.

As you can see, “cm” is 1/100th of a meter. Simply put:

1 m = 100 cm.

This means that to convert, you must multiply the available value by 100. For example:

25 m = 25*100 = 2500 cm

Such tasks are quite often faced by parents of schoolchildren. But even many decades after graduation, many adults are confused by the metric system of length measurement. There are a lot of prefixes: milli-, micro-, deci, centi-, kilo-. Let’s get into the subject a little bit.


How to convert meters to millimeters (M to MM)

The gist is as follows:

1 m = 100 cm

1 cm = 10 mm.

So to convert meters to millimeters, you have to multiply the initial value by 1000.

Example:

30 m = 30*1000 = 30000 mm


Decimeters

1 dm = 10 cm = 100 mm = 0.1 m

That is, there are 10 dts in 1 meter, so you only need to multiply the base quantity by 10 to convert.

Example:

40 m = 40*10 = 400 dm


How do you convert M to KM and back?

As you have already understood, a “meter” is an international unit used to calculate the distance or length of any object. Virtually all countries use this system, apart from the United States and a few others.

But the “kilometer” is a compound term that has the prefix “kilo”, translated into Russian as “a thousand:

Deciphering

It is the largest measure that can be converted exclusively to mm, cm, dm and m. There is one simple rule worth remembering here:

In the process of converting to larger units you have to use a division operation. And if the conversion goes from larger units to smaller units…then multiplication is used.

1 km = 1000 m

1 meter = 0.001 km

That is, according to the rule, to get the number of meters we multiply kilometers by a thousand, and if it is worth translating the other way around, we divide by 1000.

Example:

53 km = 53*1000 = 53,000 m

650 m = 650/1000 = 0.65 km

For many years, manufacturers of student notebooks have placed auxiliary tables of this type on the back:

You can print out these images for yourself and mark them up prominently if you often have to use conversions of measures.


Online Calculator

If you need to convert meters to kilometers online, so as not to bother your head with unnecessary calculations, online services with extensive functionality come to your aid.

But first we would like to tell you about the standard Windows 10 tool.

  • Run the built-in application “Calculator”(can be found through the search bar or in the list of programs);
  • In the upper left corner click on the “list” icon (three horizontal bars), in the list that appears we see the “Converter” section, and inside – “Length”;
Windows 10 Calculator -
  • Now just specify the directions of conversion and enter the values in the upper field, and the converted value appears at the bottom.

It works the same way with other measures. For example, “Speed”. This is very relevant – How to convert meters per second to kilometers per hour?

If you do not have such a miracle tool at hand, it is realistic to manually convert KM to H to M to S. The formula is simple – multiply or divide by 3.6:

1 m/s = 1*3.6 = 3.6 km/h

1 km/h = 1/3.6 = 0.277778 m/s

For example,

130 m/s = 130 * 3.6 = 468 km/h

250 km per hour = 250/3.6 = 69.44 m/s

And now we can move on to look at the online toolkit.

  • UnitJugler – the site has a fairly large selection of converters. Immediately following the link you will find yourself on the page of converting measures of length. On the left you enter your number, and on the right you will see the result. Below you can choose other units.

  • TranslatorsCafe – the essence is similar, but there is less advertising, the information is neatly grouped.

Even in the search line of Yandex you can make calculations. For example, write the query: “256 m in km”, and you immediately get the solution:

Here you have figured out how to translate meters into centimeters, millimeters, decimeters, kilometers, convert units of speed, length. I’m sure the topic is simple and straightforward. Once you remember it, and then you can count in your head.
