SI (International System of Units)

**The metric system** *or* **units of metric measurements** were standardized in 1799. The system was created in France and is an *international* measurement system. It is based on the **meter** (a unit of length) and the** kilogram** (a unit of mass). Although the system has changed a bit over time, it is still the most popular measurement system used in the world and in all sciences (Sciencing, 2017).

The **gram** was the first unit defined as * a unit* of

The kilogram is the * standard* unit of

The standard unit of** volume** is the ** liter**.

One** liter** is equal to *1,000 cubic centimeters* in **volume** measurements.

The unit of** area** is the** acre**.

The system is based on a **measure of 10.**

This allows* conversions* from different units more easy, such as, simply moving a

For example: 1 millimeter is equal to 0.001 meter;

a centimeter, which is a unit 0.1 larger than a millimeter, is 0.01 meter.

The **staircase** is used to convert from one unit to another in the metric system and is easy to use as a staircase is to climb.

**The staircase represents how the different units within the metric system are related.**

The **main units** - meter, liter, & gram are the** middle** step.

**All** of the * units above and below the base units* are the

For example: 1 meter is equal to 1000 millimeters.

1 gram is equal to 0.001 kilograms.

In order to convert from one metric unit to the other* you follow* the staircase.

When **moving down** the staircase **you multiply by 10** for each step you go down.

When **going up** the staircase you **divide by 10** for each step you go up.

**Why Our Students Need to Learn the Metric System**

All Scientists throughout the world utilize the metric system for their measurements. This system of measurement is universal and makes it possible for scientists from all over the world to understand and agree upon the measurements taken within an experiment.

Although, students in the US struggle with understanding the Metric system, it is important that they recognize the Metric system is the international form of measurement and that without this knowledge, they will be far behind the times in our ever expanding world of science and mathematics.

This base 10 system (of the metric conversion) is much simpler to use than our customary system and is essential for higher elements in mathematical thinking and understanding.
