The Units of Measurement

In the EMS setting, we worry about three metric units of measurement…

  1. Grams (g) – weight
  2. Meters (m) – distance
  3. Liters (L or l) – volume

Attached to these units of measurement will be one of the following…

  1. Kilo – one thousand (1,000)
  2. Centi – one hundredth (.01)
  3. Milli – one thousandth (.001)
  4. Micro – one millionth (.000001)

  • Milligram (mg)
  • Microgram (mcg)
  • Centimeter (cm)
  • Liter (L)
  • Milliliter (ml)
