Unformatted text preview: SI Measurement The International System of Units, or SI, is the standard system of measurement used by many scientists. Using the same standards of measurement makes it easier for scientists to communicate with one another. SI works by combining prefixes and base units. Each base unit can be used with different prefixes to define smaller and larger quantities. The table below lists common SI prefixes. SI Prefixes Prefix kilohectodekadecicentimillimicroAbbreviation k h da d c m Factor Example 1,000 kilogram, 1 kg = 1,000 g 100 hectoliter, 1 hL = 100 L 10 dekameter, 1 dam = 10 m 1 meter, liter 0.1 decigram, 1 dg = 0.1 g 0.01 centimeter, 1 cm = 0.01 m 0.001 milliliter, 1 mL = 0.001 L 0.000 001 micrometer, 1 m = 0.000 001 m SI Conversion Table SI units Length kilometer (km) = 1,000 m meter (m) = 100 cm centimeter (cm) = 0.01 m millimeter (mm) = 0.001 m micrometer (m) = 0.000 001 m nanometer (nm) = 0.000 000 001 m Area square kilometer (km2) = 100 hectares hectare (ha) = 10,000 m2 square meter Volume liter (L) = 1,000 mL = 1 dm3 milliliter (mL) = 0.001 L = 1 cm3 microliter (L) = 0.000 001 L Mass kilogram (kg) = 1,000 g gram (g) = 1,000 mg milligram (mg) = 0.001 g microgram (g) = 0.000 001 g 1 kg = 2.205 lb 1 g = 0.035 oz 1 lb = 0.454 kg 1 oz = 28.349 g 1 L = 1.057 fl qt 1 mL = 0.034 fl oz 1 fl qt = 0.946 L 1 fl oz = 29.575 mL (m2) = 10,000 cm2 square centimeter (cm2) = 100 mm2 1 km2 = 0.386 mi2 1 ha = 2.471 acres 1 m2 = 10.765 ft2 1 cm2 = 0.155 in.2 1 mi2 = 2.590 km2 1 acre = 0.405 ha 1 ft2 = 0.093 m2 1 in.2 = 6.452 cm2 From SI to English 1 km = 0.621 mi 1 m = 3.281 ft 1 cm = 0.394 in. 1 mm = 0.039 in.
