1. Dimensional Analysis

2. A method to convert from one unit of measure to another, using conversion factors.
Example Problem:
How many centimeters are in 4.6 kilometers?
Add anything in BLUE writing on the back of the foldable flap
Dimensional Analysis

3. STEP 1 Write down what you know, with units! What I know:
4.6km
What I am looking for: cm
FRONT of Flap:
Write down what you know, with units.
STEP 1
BACK of Flap:
What I know:
4.6 km
What I am looking for: cm
STEP 1

4. Set up a T-chart
4.6km
STEP 2

5. Fill in the units first, making sure that the given units cancel out.
4.6km m km
STEP 3

6. STEP 4 100 cm 1 m = Add your key conversion factor into your T- chart.
Multiply across the top, divide by the bottom
**If necessary, continue steps 3 and 4 until you reach your desired answer.
4.6km 1000 m
1 km
100 cm
1 m
(4.6*1000*100)
(1*1) =
= 460,000cm
But I’m looking for centimeters!
STEP 4

7. Key Conversion Factors
1cm = 10mm
1m = 100cm
1m = 1000mm
1 km = 1000m
*The base units (meters) can be changed to other units (grams, liters, etc).
