    FAQ

    How many milligrams is 258 mcg?

    258 mcg = 0.258 mg

    What is the formula to convert 258 mcg to mg?

    To convert micrograms to milligrams, divide the microgram value by 1,000. So 258 mcg ÷ 1,000 = 0.258 milligrams.

    Why does confusing mcg with mg matter on a label?

    Because the two differ by a factor of 1,000: 258 micrograms is only 0.258 milligrams. Vitamin D, folic acid and levothyroxine are dosed in micrograms for exactly that reason — reading mcg as mg would mean a thousandfold overdose.
