Medication Unit Conversion Practice Questions
Practise the same-dimension conversions used in medication maths. Work through g, mg and mcg; L and mL; hours and minutes; and source-supplied lb-to-kg questions while keeping the value and unit together.
Medication unit conversion practice
Quick review before you start
Name the starting unit and target unit first, then apply the correct relationship and check whether the number should grow or shrink. Metric relationships such as 1 g = 1000 mg and 1 mg = 1000 mcg convert the same quantity into a different unit; they do not turn mass into volume.
Formula
1 g = 1000 mg; 1 mg = 1000 mcg; 1 L = 1000 mL; 1 hr = 60 min
mg and mL are different kinds of quantities. A mass-to-volume calculation requires a concentration, so it belongs to a dose-to-volume problem rather than a simple unit conversion.
Sample question
Convert 0.125 g to mg.
0.125 g × 1000 mg/g = 125 mg
Answer: 125 mg
What these questions practise
- g to mg and mg to g
- mg to mcg and mcg to mg
- L to mL and mL to L
- hours to minutes and minutes to hours
- lb to kg only when the problem supplies pounds and requires kilograms

What the learning states mean
Learned means the lesson is complete. Practised means you have attempted questions. Secure requires a strong unassisted run. Mastered requires strong evidence again after time has passed. Review due means a previously stronger skill is ready for retrieval again.
