How many pounds is a kilogram?
1 kilogram = 2.20462 pounds, and 1 pound = 0.45359237 kg exactly (the international definition). A quick clinical shortcut: halve the pounds and take 10% off to estimate kilograms — 50 lb ≈ 22.7 kg.
How many micrograms are in a milligram?
1 milligram = 1,000 micrograms (µg), and 1 gram = 1,000 mg = 1,000,000 µg. The mg-to-µg step is the classic source of 1000× dosing errors with drugs like dexmedetomidine and fentanyl, which is exactly why a converter beats mental math at 2 a.m.
Why do veterinary doses use kilograms?
Nearly every drug dose is published per kilogram of body weight (mg/kg or µg/kg), while clients usually report weight in pounds. Converting accurately first — not rounding — keeps narrow-margin drugs inside their safe range for small patients.
