How do you work out how much iob aka unused insulin aka bob you have left after a certain length of time if you're not on a pump?
 
I was told to assume a flat profile over 4 hours - a quarter of the insulin is used each hour.
So, if I took 8 units at midday, I would have
- 6 unit of IOB at 1pm
- 4 units at 2pm
- 2 units at 3pm
- none at 4pm

Why are you asking?
What calculations are you making that needs to know iob?
