this thought just came up in relation to another thread. i know a cc is NOT the same as a unit, but what is the difference exactly? why are some insulins measured in cc's and some in units?
? can someone clarify cc's vs units?

Insulin is measured in units, abbreviated U
(international units, previously abbreviated IU).
One unit of insulin is defined as the amount of
insulin that will lower the blood glucose of a
healthy 2 kg (4.4 lb) rabbit that has fasted for
24 hours to 2.5 mmol/l (45 mg/dl) within 5
hours
From:

All human insulin except for a couple of special cases, is U100, that means there is 100 units of insulin in 1 ml. Pet-only insulins like ProZinc are U40, 40 units per ml.
One special case human insulin is the new Toujeo which is U300.

As Larry says, insulin is measured in 'units'.
A 'cc' is a cubic centimetre.
A 'cc' has the same volume as a millilitre ('ml').
Where the confusion lies may be in the fact the insulin 'strength' is referred to in terms of how many 'units' it has per 'ml'; ie, whether it has 40 units per ml (U40), or 100 units per ml (U100).
Syringes are also referred to by their volume in ml.
Not sure if this helps or just confuses the issue further...
