How do you convert 5000 iu vitamin D into mcg?

To convert mcg to mg:

Divide by 1000

OR

multiply by 0.001

OR

move the decimal 3 places to the left

(they all mean the same thing),

so 500mcg = .5mg. Similarly, 1000mcg = 1mg, 2500mcg = 2.5mg, etc.

AND to convert in the opposite direction, mg to mcg, multiply by 1000,

so 3mg = 3000mcg, 1.5mg = 1500mcg, etc.
