Concept 1 Unit Conversionis

(Meters)
Kilometers
Hectometer
Dekameter
Meter
Decimeter
Centimeter
Millimeter
Those are all the units for the metric system. A very good pneumonic device that I use is Kangaroos Hop Down Mountains During Cold Months.

Example 1:
60 m/s to km/hr

So we first know that there are 60 meters per second. 60m/1s
We also know that there are 3600 seconds per hour 3600s/1hr
Right now the equation should look like this: 60m/1s X 3600s/1hr
We still need to get the meters into kilometers.
So we think to ourselves how many meters are in a kilometer? 1000
That part of the equation should look like this 1km/100m
The full equation is supposed to look like this: 60m/1s X 3600s/1hr X 1km/100m.
Then multiply the top, and the bottom 216000/1000
Your answer should then be 216 km/hr
