Hi Sharon,

ug and mcg are both symbols for 'micrograms'. The correct symbol for microgram is actually µg. However, there is no way of typing that on a keyboard, so they came up with other versions, two of which are ug and mcg.

If you wish to convert micrograms (ug or mcg) to milligrams, you can use this converter:

There is a way to type that u in ug correctly. Press your ALT key, keep it down and key in 0181 from your number pad and it makes µ.
