September, 23 2010 - Unit Conversion

On September, 23 2010 we reviewed and went further on unit conversion.
We did a lot of review sheets and went over them.

Converting units might be confusing and hard to deal with. There is one way how I remember it.
starting from small it goes k<M<G<T<P. KMGTP.
There's the da, deca for decades.

Say you have to convert 20km to dm.

The equation would be 20km*(10, 000dm/1km) .
The km will get canceled and u will be left with dm.
I always put the unit ur converting from which is km on the bottom first  and then think how many dm there is in a km.  1km = 1000m 1dm = 0.1m which is 10dm = 1m then 1km = 10, 000dm and then just times that by 20.
Here's a chart for you to look at.

And here's a video for you to look at as well.
