Dimensional Analysis

Dimensional analysis is the technique of converting between units.

There are only four steps for this technique.

1. Identify what units you want to end up with
2. Find the conversion factors
3. Place units in the appropriate places
4. Cancel units

Ex:

How many seconds are in 1.4 hours?
1.4h x 3600s/1h = 5040s

Ex.

What is 50km/h in m/s?
50km/h x 1h/3600s x 1000m/1km = 13.88888889
                                                     =14m/s
