Conversion Problems  King Henry Died __base unit__ Drinking Chocolate Milk  We could express how each of the prefixes is related to each other using equivalencies  Real life example  $1 = 4 quarters = 10 dimes = 20 nickels = 100 pennies  Metric example  1 meter = 10 decimeters = 100 centimeters = 1000 millimeters  If we set 2 measurements that are equal to each other up as a ratio, the ratio will equal 1. These are conversion factors (a ratio of equivalent measurements).

Conversion Problems  When a measurements is multiplied by a conversion factor, the actual size of the measurement remains the same, however the numerical value will change because the prefix for the unit is changing.
