# How to use the metric system.

### Colin M. Tillery

## 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.

**This picture shows the SI unit stair step, used commonly among students.**

## Create an acronym for the stair step to help your reader remember the order.

- Donuts
- But
- doesn't
- carry
- donuts

## 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.
