Set A Money Time DollarsHour Length (Length x Force)/ Time Length x Force (Money/ Length) ( Force) Cm^3 Foot pounds per second Newton Meters Cents per Kilowatt 3

Set B Acceleration x d = speed (Miles/Hour) / Sec x d = Miles/ Hour (Miles/ Hour) x (1/ sec) x d = Miles/ Hour (1/sec) x d = (Miles/Hour)/(Miles/Hour) (1/sec) x d = 1 D= sec Sec= Time (Miles/Hour) / Sec x d = Miles/ Hour (Miles/ Hour) x (1/ sec) x d = Miles/ Hour

Set C $30,000 per working year= $30000 Working year X 1 work year 52 work weeks 1 work week 5 work days X 1 work day 8 hours $14.2 Work hour =X

Set D While Betty and Jim were on a 2 week vacation, they left a 150 watt light bulb burning. If their power company charges 8 cents per kilowatt hour of electricity, what did leaving the light on cost them? 150 watt X 2 weeks X 1 kwh 1000 watt X 7 days 1 week X 24 hours 1 day X 8 cents 1 kwh X $1 100 cents = $4.03

Model Exam Which of the following are dimensionally equivalent? a) Kilowatt hours b) Dollars per cubic centimeter c) Newton meter seconds d) Joules e) Centimeters per acre foot f) Miles per hour g) Calories A, D, G are dimensionally equal B, E are dimensionally equal

Model Exam Perform the following conversions: a) 944 calories to Joules= 3950 Joules b) 59 in^3 to cm^3 = 967 cm^3 c) Would you rather sell your wheat for $4.94 per bushel or 339 DM per metric ton? (1 DM= $0.56 ) 4.94 $/ bushel = DM/ metric ton Thus 339 Dm/metric ton is the better price.

Applications in the Real World Chemistry: Stoichiometry, when converting grams to moles Food: When converting cups to pints in recipes Nutrition: When converting calories to different units of energy Product Comparison: When comparing savings, how much each ounce is priced

USA and the Metric System Why won’t the US convert to the Metric System?? Contact the President’s Science Advisory Board to petition the change:
