Just a brief conversion I know this came up a lot on the old board.
1 cc (cubic centimetre) = 1 ml (milliliter ) these are volume measurements.
A mg measures the dosage of the drug a mg = 1/1000 of a g (gram)
1 mcg (microgram) = 1/1000 milligram
An IU (International Unit) is a measurement of fluid
So:
10cc = 10ml
Take Sust 250mg/ml = 250mg (The strength of the drug or dosage) per ml of fluid.So if you wanted to use 500mg this would require 2ml
If you are not sure always check prior to injecting/swallowing
Be Safe
