Dimensional Analysis

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

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

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:

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

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

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