What is the formula to convert 3 mcg to mg?

Why does confusing mcg with mg matter on a label?

Because the two differ by a factor of 1,000: 3 micrograms is only 0.003 milligrams. Vitamin D, folic acid and levothyroxine are dosed in micrograms for exactly that reason — reading mcg as mg would mean a thousandfold overdose.
