# How to use the metric system.

## What is 'SI'? What does it stand for? History of SI?

It includes weights, measures, metric, and non-metric systems. It stands for the International System of Units. Archives de la République in June 22 1799 created the first step in the SI.

## Why are SI unit and metric system so useful and important.

• They are useful and important because almost every scientist use the SI system.
• It is the major units used in almost every country
• it is taught in about every country

## what are the SI base units and abbreviations for length, volume, mass, temperature, and time.

• length-meters-m
• volume- liter-l
• mass- gram- g
• temperature- kelvin- k
• time- second- s

## What is the metric unit stair step?

• It is a way for converting metric units to other units
• Also it is used by most students
• In my opinion it is the easiest way to convert.

## How to go from something smaller to larger

• When you go from a small number to a large number you move the decimal to the left.
• example- 12.07 cm= .1207 m
• example- 170.37mm= .17037m

## How to go from something larger to something smaller

• When you go from a large number to a smaller number you move the decimal to the right.
• example- 12.07km= 12070 m
• example- 145.9cm= 1459mm

## 8 example using the stair step method

• 12.57g= .1257hg <--------
• 177.5mm= 17.75cm <-------
• 1.35hg= .135kg <-------
• -------> 7.7kg= 77hg
• ---------> 97.67cm= 976.7mm
• -----------> 10.12m= 1012cm

## concluding statement

If you ever can't figure out how to convert decimals use the stair step process.
