Conversion Factors
If we have 4 kilometers how many cm do we have?
? centimeters = 4 kilometers X ( 1000 meters/ 1 Kilometer)* X (100 cm/ 1 meter)* =400,000 cm * (conversion factor)
3 quarter = how many dollars
? dollars = 3 quarters x (1 dollar/ 4 quarters)* = [3/4] = .75 dollar *(conversion factor)
4 quarters = how many dollars
? dollars = 4 quarters x (1 dollars /4 quarters)* = 1 dollar *(conversion factor)
If we have 1 meter how many kilometers do we have?
? kilometer = 1 meter x (1 kilometer/ 1000 meter)* =[1/1000] = .001 kilometers *(conversion factor)
If we have 1 meter how many millimeters do we have?
? millimeter = 1 meter X (1000 millimeter/ 1 meter)* = 1000 millimeters *(conversion factor)
2.5 dollars = how many quarters
? quarters = 2.5 dollars x (4 quarters/ 1 dollars)* =[2.5 x 4] = 10 quarters *(conversion factor)
Conversion Factors
use dimensional analysis and are also used in dosage problems A/B is Equal to B/A for example 100 cm/1 m is equal to 1 m/ 100 cm conversion factors can be flipped as it fits in equation.
