Dimensional Analysis: Lesson 6
Want to know how to convert km/hr to mi/hr?Just like converting between curencies in Chemistry it is usually necessary to convert between units
This process is called Dimensional Analysis
Steps:
- Find the unit equality
- Find the conversion factor
- Apply conversion factor
- Cancel units
Example: 3 600s = 1 hour
(2.4 hr) (3600s/ 1hr) = 8640 s
Example: What is 100km/hr in m/s?
1 km = 1000 m
1 hr = 3600s
(100 km/hr)(1000m/1 km)(1 hr/ 3600s) = 27.8m/s
Example:How many seconds are in a day?
