Chemistry 134 Metric Conversion Practice Problems Two ways to think about metric conversions 1x10 -9 meters = 1 nanometer or 1 meter = 1x10 9 nanometers 1x10 -6 meters = 1 micrometer or 1 meter = 1x10 6 micrometers 1x10 -3 meters = 1 millimeter or 1 meter = 1x10 3 millimeters 1x10 -2 meters = 1 centimeter or 1 meter = 1x10 2 centimeters 1x10 -1 meters = 1 decimeter or 1 meter = 1x10 1 decimeters 1 meter = 1 meter or 1 meter = 1 meter 1x10 1 meters = 1 dekameter or 1 meter = 1x10 -1 dekameters 1x10 3 meters = 1 kilometer or 1 meter = 1x10 -3 kilometers 1x10 6 meters = 1 Megameter or 1 meter = 1x10 -6 Megameters How were the above conversions accomplished? The relationship between meters and nanometers (left column) is that 1x10 -9 meters = 1 nanometer. To determine how many nanometers are in 1 meter, we simply divide both sides of the equation by the number of meters. 1 " 10 # 9 m = 1 nm 1 " 10 # 9 m 1 " 10 # 9 = 1 nm 1 " 10 # 9 1 m = 1 " 10 9 nm Another example is the conversion between kilograms and pounds (1 pound = 2.2046 kilograms). Again, we can determine how many pounds are in a

You are not expected to memorize the English-to-metric conversion factors . 1 lbs = 2.2046 kg 1 lbs 2.2046 = 2.2046 kg 2.2046 0.4536 lbs = 1 kg Practice Problems: Perform the following conversions and express the answers in both decimal notation and scientific notation, along with the proper metric abbreviation (i.e. 62.2 milliliters = 62.2 mL = 6.22x10 1 mL). (1) 170.4 meters = ? centimeters (2) 564 dekagrams = ? grams (3) 58 decigrams = ? milligrams (4) 600 liters = ? kiloliters (5) 0.0923 kilometers = ? millimeters (6) 0.49 grams = ? micrograms (7) 21.001 centiliters = ? deciliters (8) 4.51x10-3 milliliters = ? nanoliters (9) 45700 centigrams = ? micrograms (10) 24.6 kilograms = ? milligrams (11) 82.4 nanoseconds = ? dekaseconds (12) 1.2 Megameters = ? kilometers...
