1.Easy
kg× 1000g× 1000mg× 1000mcg0.2 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.2 g to mg: find x.

0.2 g1 g = 1000 mg
x = mg
2.Easy
L× 1000mL0.1 L?

Practice exercise (made-up values, not clinical guidance). Convert 0.1 L to mL: find x.

0.1 L1 L = 1000 mL
x = mL

94969810010210410635363738394041°F°C102.3 °F? °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 102.3 °F. Convert it to degrees Celsius T with °C = (°F − 32) × 5/9. Round to one decimal place.

102.3 °F
T = °C
4.Medium
6.0064 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 6.0064 mL. The rule in this exercise is that volumes of 1 mL or more are rounded to the nearest tenth of a mL. What value x do you record?

6.0064 mL
x = mL
5.Hard
1½ tsp · 3/day · 5 d? mL1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). A prescription reads 1½ tsp of an oral suspension every 8 hours for 5 days. Using 1 tsp = 5 mL, how many mL V are needed for the whole course?

1½ tspevery 8 hours5 days1 tsp = 5 mL
V = mL
6.Hard
25 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 25 mcg/min. Express this dose rate D in mg/h.

25 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h

Answer key

  1. 1. x = 200 mg
  2. 2. x = 100 mL
  3. 3. T = 39.1 °C
  4. 4. x = 6 mL
  5. 5. V = 112.5 mL
