10 metric conversions and unit analysis

We are going to use unit analysis to do some metric conversions.

The main purpose of this is to learn unit analysis and secondly learn about metric conversions.

To facilitate this you are only allowed to convert by 103 x per conversion.

Please do the same in your workbook. We use unit analysis as our main calculation tool in Chemistry 11 and Chemistry 12.

Learn it well and you will do awesome in chemistry.


10 metric conversions and unit analysis

1. Convert 1.23 x 1012 Mm to m- you can only convert by 103 in any one step!

1.23 x 1012 Mm

x 1 x 103 km

x 1 x 103 m

1 Mm

1 km

=1.23 x 1018 m

Write the starting number and units

Multiply with 1 Mm on the bottom and 103 km on top

Mutiply with 1 km on the bottom and 103 m on top

Do the math and round off to three sig figs
