Unit rate: Amount per 1 unit of another quantity — e.g. $3 per pound
Finding a unit rate: Divide the first quantity by the second — 120 ÷ 4 = 30 per unit
Conversion factor: A fraction = 1 for converting units — e.g. 60 min/1 hr
Dimensional analysis: Multiply by conversion factors, canceling units you don't want
1 foot = ? inches: 12 inches
1 yard = ? feet: 3 feet
1 mile = ? feet: 5,280 feet
1 pound = ? ounces: 16 ounces
1 meter = ? centimeters: 100 centimeters
1 kilometer = ? meters: 1,000 meters
Best unit price: Find unit rate for each option (cost ÷ quantity); lower unit price = better deal
Metric system base: Powers of 10 — kilo=1000, centi=1/100, milli=1/1000
