Can someone explain this practice oral dosage question?

"The order is for 30,000 mcg of a medication to be given PO QID. The label reads that each tsp contains 15mg of the medication. How much mL will the patient need per day?"

I know the answer is 40 mL, I just want to learn how to solve the question.

    (30,000 μg) * (1 mg / 1000 μg) * (1 tsp / 15 mg) * (~4.9 mL / tsp) = 9.8 mL

  • 30,000 mcg = 30 mg

    15 mg per teaspoon means that you'll need 2 teaspoons. You're going to take this dosage 4 times per day, so that's 8 tsp. 1 tsp = 4.92892 mL

    8 * 4.92892 =>

    4 * 9.85784 =>

    2 * 19.71578 =>

    39.43156

    You can round up to the nearest mL, I suppose. 40 mL
