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: • KHDMDCM • King Henry Danced Merrily Down Center Main Lightly Gracefully
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
