Document Summary
One step multiple conversions: multiple conversions may be set up in one step. (79,510 s) x (1 min/60 s) x (1 hour/60 min) = 22. 09 hours. Compound units: a compound unit is made up of two or more units, compound units are speci c situations and may change as the situation changes, compound units can be used as conversion factors, ex. 89 cents per pound equation= 89 cents = 1 pound conversion factor= 89 cents/1 pound or 1 pound/89 cents. Conversion factors: both conversion factors and simple compound units, by de nition, equal to 1 are invertible. However, conversion factors are constant through space and time while compound units may vary with time, location, and situation. Using compound units: a poodle has a prescription for 125 mg of penicillin to be taken 4 times a day. The pharmacy dispenses a solution that is 250 mg/5 ml.
