2. Dimensional Analysis
Dimensional Analysis is a scientific method of converting one unit of measurement to another using equalities called “conversion factors.”

3. What do you need to know to use dimensional analysis?
Any number divided by itself = 1
EX: 2/2 = 1
0.7/0.7 = 1
156/156 = 1
1 min / 60 sec = 1
5280 ft / 1 mile = 1
1 meter / 1000 mm = 1
10 hm / 1 km = 1

4. What do you need to know to use dimensional analysis?
To use dimensional analysis for converting metric units to other metric units, you should know the ORDER of metric prefixes:
KHDMDCM
King Henry Danced Merrily Down Center Main
Lightly
Gracefully

5. What do you need to know to use dimensional analysis?
You need to know certain CONVERSION FACTORS.
A conversion factor is a fraction that is equal to 1 because the values on top and bottom are equal.
1 min / 60 sec = 1
5280 ft / 1 mile = 1
1 meter / 1000 mm = 1
10 hm / 1 km = 1

6. How Does DA work? 2 hours = ___ seconds 25 sec = ___ hr 5 ft = ___ yd
2.7 mi = ___ in

7. DA using metrics 30 cm = ___ km 4 hm = ___ dkm 67 g = ___cg
34 L = ___kL
6 hg = ___ mg
2 km = ___ mm
5 mm = ___ km
