Key concepts

  • Metric System of Measurement
    • Length
      1 kilometer (km) = 1,000 m 1 hectometer (hm) = 100 m 1 dekameter (dam) = 10 m 1 meter (m) = 1 m 1 decimeter (dm) = 0.1 m 1 centimeter (cm) = 0.01 m 1 millimeter (mm) = 0.001 m 1 meter = 100 centimeters 1 meter = 1,000 millimeters
    • Mass
      1 kilogram (kg) = 1,000 g 1 hectogram (hg) = 100 g 1 dekagram (dag) = 10 g 1 gram (g) = 1 g 1 decigram (dg) = 0.1 g 1 centigram (cg) = 0.01 g 1 milligram (mg) = 0.001 g 1 gram = 100 centigrams 1 gram = 1,000 milligrams
    • Capacity
      1 kiloliter (kL) = 1,000 L 1 hectoliter (hL) = 100 L 1 dekaliter (daL) = 10 L 1 liter (L) = 1 L 1 deciliter (dL) = 0.1 L 1 centiliter (cL) = 0.01 L 1 milliliter (mL) = 0.001 L 1 liter = 100 centiliters 1 liter = 1,000 milliliters
  • Temperature Conversion
    • To convert from Fahrenheit temperature, F, to Celsius temperature, C, use the formula C = 5 9 ( F 32 )
    • To convert from Celsius temperature, C, to Fahrenheit temperature, F, use the formula F = 9 5 C + 32
