Question

When converting a drug dosage from mg/kg to μg/g, what conversion factors are used?

Options

• 1 mg = 100 μg and 1 kg = 100 g

• 1 mg = 1000 μg and 1 kg = 1000 g

• 1 mg = 10 μg and 1 kg = 10 g

• 1 mg = 1 μg and 1 kg = 1 g

Answer 1

1 mg = 1000 μg and 1 kg = 1000 g

Reason:

The correct SI conversion factors are 1 mg = 1000 μg (1 milligram equals 1000 micrograms) and 1 kg = 1000 g (1 kilogram equals 1000 grams).
