  1. MEDICAL MATH

  2. Math Conversions • Length • 1 meter = 100 centimeters = 1000 millimeters • 10 millimeters = 1 centimeter • Weight • 1 gram = 1000 milligrams • 1 milligram = 1000 micrograms • 1 kilogram = 1000 grams

  3. Volume for Solids • 1000 cubic millimeters = 1 cubic centimeter • 1000 cubic centimeters = 1 cubic decimeter • 1000 cubic decimeters = 1 cubic meter • Volume for Fluids • 1 liter = 1000 milliliters • 1 milliliter = 1 cubic centimeter • 10 centiliters = 1 deciliter

  4. Weight Conversion • 1 kilogram = 2.2 pounds • 1 pound = 16 ounces • 1 ounce = 0.028 kilograms • Temperature Conversion • °C = (°F-32) 5/9 or 0.5556 • °F = (°C) 9/5 or 1.8 + 32

  5. Equivalents (Note: 1 cc = 1 mL) • Metric Household • 1 cc or 1 mL 15 gtts (drops) • 5 mL or cc 1 tsp (teaspoon) • 15 mL or cc 1 tbsp (tablespoon) • 30 mL or cc 1 oz (ounce) • 240 mL or cc 1 cup (8 oz.) • 500 mL or cc 1 pt (pint) (16 ounces) • 1000 mL or cc 1 qt (quart) (32 ounces) • 1 meter 39.372 inches (3.281 feet) • 0.914 meters 3 feet (1 yard) • 0.3048 meters 12 inches (1 foot) • 2.54 centimeters 1 inch

  6. Setting up operationMedications • ORDERED AVAILABLE XQUANTITY Dr. orders: 15 mg MSO4 IV prn pain Available: 25 mg/ml MSO4 15 mg 25 mg x 1 ml = 0.6 ml EXAMPLE:

  7. Calculating WEIGHT • 2.2 is the conversion factor • 1 kg (kilogram) = 2.2 lbs • From lbs to kg: you divide • From kg to lbs: you multiply • Example: 150 lbs / 2.2 lbs per kg =68.18 kg • 68 kg x 2.2 lbs per kg =149.6 lbs

  8. Calculating Temperatures • C = (F-32) 0.5556 • F = (C) 1.8 + 32 • Convert these temps • 36 degrees C=_______F • 101.4 degrees F = _______C
