Unit: is activity. You will need the definition of 1 insulin unit, don't
know what that is though. Could be the "amount of insulin needed to
convert 1 mole of sugar residues into... within 1 hour"
Then you will have to know, how many units per mole are in your tube.
If the batch of insulin that you have contains a lot of inactive
insulin molecules, this number gets lower.

basically, you will either need the sheet from the pharmaceutical
company, or a good text book on insulin, or a catalog from Sigma, or Boehringer
