Hello welcome to MooMooMath where we upload a new math video everyday.
Today I would like to talk about the metric system
The metric system is a system of measurement used throughout the world, and the scientific community.
It is based on tens, and can be easy to use.
Let’s begin with some basic units of measurement.
Lets start with seven frequently used units of the metric system.
Starting at the left and moving to the right, we have,
Kilo, Hecto, Deka, Base Unit, Deci, Centi, Milli
Starting at the base unit, and moving to the left, the deka would have a value of 10 , hecto a value of 100’s, and a kilo a 1000.
Next, if you start at the base and move to the right a deci is 1/10,centi is 1/100, and milli is 1/1000
Now let’s talk about the base units.
There are three main base units, and they give you a clue as to what is being measured. A meter is used for length, a liter for volume, and a gram for measuring mass.
All three of these base units are related.
A meter is 1/10 millionth the distance from the North Pole to the equator, on a meridian that passes through Paris.
If you take this distance and divide it into 10 million small units, you have a meter.
If you divide the meter into 10 equal parts you have 10 decimeters. If you divide a decimeter in tenths you have created a centimeters. If you divide the centimeter into 10 small parts you have a millimeter.
On the other hand, if you have 1000 meters you have 1 kilometer.

A liter is the volume of one cubic decimeter.
You can see how they are related.
A liter the volume of one decimeter.

Again you can subdivide the liter into a centiliter which is 1/10 of a liter.
A gram is equal to the mass of 1 cubic centimeter of water.
Finally let’s look at one more example of how the metric system works.

If you measure a distance of 5 kilometers this will be equal to 50 Hectometers, 500 dekameters, 5000 meters, 50,000 decimeters,500,000 centimeters, 5,000000 millimeters

One nice characteristic of the metric system is how easy it is to convert from one unit to another.
I have created another video on how to convert within the metric system.

Hope this helps, and MooMooMath uploads a new Math video everyday.
