    FAQ

    How many milligrams is 558 mcg?

    558 mcg = 0.558 mg

    What is the formula to convert 558 mcg to mg?

    To convert micrograms to milligrams, divide the microgram value by 1,000. So 558 mcg ÷ 1,000 = 0.558 milligrams.

    Why does confusing mcg with mg matter on a label?

    Because the two differ by a factor of 1,000: 558 micrograms is only 0.558 milligrams. Vitamin D, folic acid and levothyroxine are dosed in micrograms for exactly that reason — reading mcg as mg would mean a thousandfold overdose.
