**Metric conversion** in mathematics is certainly always used in everyday life because it is very useful to be able to measure the length of an object or a distance traveled. For example, you wonder how far you have traveled from home to your office.

Maybe you want to measure your height to see how your height changes over time. So, it is undeniable that the conversion of the unit of measure of length is simple mathematics that is needed by all people, whether they are still in school or for work.

**Basic Concept of Metric Conversion**

Nowadays, measuring the length of an object is also very easy because there are already special tools created to measure length, and also distance, such as a ruler that we must have at home. Each measuring instrument has its own length unit.

When you want to change a unit of length you will definitely need a ladder conversion to make it much easier. For example, if you want to convert kilometers to meters, if you don’t know the exact order, you will be confused and also wondering which one is correct.

But below there is an image that can make it easier for you so that you can count quickly and also learn to memorize the unit length conversion ladder. Learning about **metric conversion** will be useful for anything in your daily life. See Attached figure 11.1.

And below is the ladder conversion unit of length in mathematics that can help you memorize it, so that when you find a problem and are asked to convert a unit of length you don’t need to be confused anymore.

Conversion of units of length :

1 Kilometers 10 Hectometer

1 Kilometers 1000 Meter

1 Kilometers 100.000 Centimeter

1 Kilometers 1.000.000 Millimeter

1 Kilometers 10.000 Decimeter

1 Meter 100 Centimeter

1 Meter 0.001 Kilometers

1 Meter 10 Decimeter

1 Meter 0.1 Decameter

**Several Example of Metric Conversion**

After understanding the basic concept of this inversion, now we can turn to sample problems so that you can do all these math problems easily and quickly. Below we have provided some examples of questions that will make you much more familiar with working on unit length problems.

### Example Problem 1

A carpenter will join three wooden planks of 85 cm, 10 dm, and 6 m long. Calculate how long the wooden planks are when connected:

Answer: Equate the units to cm (centimeter) 85 cm + 10 dm + 6 m = 85 cm + 100 cm + 600 cm = 745 cm.

### Example Problem 2

A tiger in the meadow ran for 2 km over 500 m, then the tiger ran back after the deer for 6.5 dams. How far has a tiger traveled?

Answer: Equate the units in the form m (meters) 2 km over 500 meters = 2500 meters. 6.5 dam = 65 m. Then the result is the distance that a tiger has traveled is 2500 m + 65 m = 2565 m.

And those are some examples of questions from the discussion of unit length conversion discussed this time. It’s actually quite easy if you understand the unit of measure correctly. If you still don’t understand some of the examples above, you can review the **metric conversion** given above the table.
