A 0.4 mg/kg dose for 60 kg yields how many milligrams?

Explanation:
Calculating a total dose from a per-kilogram dose involves multiplying the dose per kilogram by the patient’s weight in kilograms. Here, 0.4 mg per kilogram for a patient who weighs 60 kg gives 0.4 × 60 = 24 mg. The units mg/kg and kg cancel, leaving milligrams as the total dose: 24 mg. If weight were given in pounds, you’d first convert to kilograms (1 kg ≈ 2.2046 lb) before multiplying.
