Question

How do you convert between units?

Answer 1

I recommend that my students use a technique called dimensional analysis which is basically like multiplying fractions.

To use this you need to identify conversion factors. Some examples of conversion factors are:
1 hour = 60 min
1m = 100cm
1km = 1000m

Here is a video of some easy conversion problems using these conversion factors solved using dimensional analysis:
