Learn who the multiples and submultiples of the meter are. The need to measure is as old as the need to count, since it was necessary to create a measurement standard that would work and always indicate the same value.

In the past, the size of the hand or arm was used as a measurement. However, these members changed their size according to each person. This hampered business transactions and made relationships even more complicated.

To minimize this problem, in the XNUMXth century, sand created the Decimal Base Measurement System in France, which had three main units: the meter (length), the liter (capacity) and the kilogram (mass). Later, in the 1962th century, the system created by the French was adopted by most of the countries of the world as the International System of Measurement (SI). Brazil, for example, adopted this characteristic in XNUMX.

## Meter: the reference measurement

The metro is the center of all measurements. It is the balance between large and small measures. Widely used in people's daily life, it is used to measure distances, sizes, etc. The multiples and submultiples come from it. This first definition encompasses all measurements that are the result of the meter's decimal multiplication. While the second refers to division. Better understand by looking at the following diagram:

### Meter multiples

### The submultiples of the meter

 Measure Acronym Relationship with the metro Decimeter dm m / 10 Centimeter cm m / 100 Mm mm m / 1000

## Transformative measures

With the schematic and table demos above, it is easy to understand how the Measure transformation works. Think that each acronym is a house, and as we move from one to another we count them. Look at the example:

Transform 20 kilometers (km) to meters (m) = From km to m they walk three houses on the right, then the calculation will be through multiplication. So, we have: 10 10 x x 10 (number of houses walked), which is equal to 1000. So 20 1000 x = 20,000. Whereby 20 km = 20. 000 metres.

Convert 3.500 millimeters (mm) into meters (m) = Counting the houses from centimeters to meters, we get two houses on the left, then the calculation will be division. Then we will have: 350/10/10/10 = 3.5. That means saying that 3.500 mm = 3,5 m.
