Metric Equivalents
If a measured quantity is expressed in 2 different metric units
1000 mm = 1 m
1.00 pg
1.00 picogram = 1.00 x 10^-12 g
1.00 um
1.00 micrometer = 1.00 x 10^-6 m
1.00 cm
1.00 centimeter = 1.00 x 10^-2 m
1.00 dL
1.00 deciliter = 1.00 x 10^-1 L
1.00 kg
1.00 kilogram = 1.00 x 10^3 g
Examples of Metric Equivalents (Length)
1,000 mm = 1 m
100 cm = 1 m
10 mm = 1 cm
Examples of Metric Equivalents (Mass)
1,000 mg = 1 g
1,000 g = 1 kg
Examples of Metric Equivalents (Volume)
1 L = 1,000 mL
