What are metric conversions

What are Metric Conversions?

  • Sometimes we need to change from one measurement to another.

  • This is usually done because the unit that is used is either too big or too small for that type of measurement.


Too big

TOO BIG !!!

525,568 millimeters

Sometimes the number is too big for the unit being measured.


Too small

Too Small

0.00654 km

Sometimes the number is too small for the unit being measured


How do we fix this problem

How Do We Fix This Problem?

We can correct these problems by doing a process called Metric Conversion. When you do a Metric Conversion, you are changing from one unit of measurement to another.


So how do i do a metric conversion

So How Do I Do A Metric Conversion?

We will be using a method called The Stair-step Method of Metric Conversion.

It requires you to move the decimal in the number.

  • -The first letter of the prefix in the unit of measurement tells you which step to start on.

  • -The first letter in the second unit of measurement tells you which step to stop on.

  • -Find which step to start on, and count the number of steps it takes to get to the step that you need to stop on.

How Do I Use This (cont.)?

  • If you went to the right(downstairs) the decimal in the first measurement moves that many places to the right.

  • If you went to the left (upstairs) then the decimal moves to the left. Fill any empty places with zeros.

525568 mm = ? m

The decimal in 525568 mm moves three places to the left, becoming 525.568 m.

0.00654 km = ? m

0.00654 km becomes 6.54 m.
