U5.3 Conversions Between Systems

U5.3 Conversions b/w Systems

1. Take notes on the slides in regards to converting between the metric system and the imperial system.

2. Answer the problems as they appear. Do your absolute best not to Google the answer as this will not help you on the quiz next Wednesday.

3. I am in the building, so you may request to come down to the blood drive for assistance. DON'T abuse it, though.
