Frequently Asked Questions
Why do medical doses use metric units?
Clinical settings use the metric system — mg, mcg, mL, L — because it is exact and globally consistent. Kitchen units like cups and teaspoons are never precise enough for medication.
How many mcg are in a mg?
Exactly 1,000 micrograms in 1 milligram (1 mg = 1,000 mcg), and 1,000 mg in 1 gram. These are fixed metric definitions that apply to every substance.
Is this medical advice?
No. These pages are educational references for nursing students and healthcare professionals. They are never a substitute for clinical judgment — always verify doses with a pharmacist or physician and follow facility policy.
