How do I convert mg to mcg?
Multiply by 1000: 1 mg = 1000 mcg. Going the other way, divide by 1000, so 500 mcg = 0.5 mg. Always write the leading zero on a value below 1.
How do I convert pounds to kilograms for a dose?
Divide the pounds by 2.2. A 44 lb child weighs 44 / 2.2 = 20 kg. Weight-based orders are written in mg/kg, so the conversion has to happen before the dose is calculated.
How many mL are in a teaspoon?
One teaspoon is 5 mL and one tablespoon is 15 mL. Household spoons vary, so a dose measured at home should be drawn with an oral syringe or a dosing cup, not a kitchen spoon.
Why does a very small conversion still show digits?
Small amounts are real doses. 1 mcg converted to grams is 0.000001 g, so the converter keeps enough decimal places for the value to be readable instead of rounding it away to zero.
