Okay, I just answered your other question. Take it you are type 1 diabetic? Here is a pdf chart of the sliding scale. https://apps.umchealthsystem.com/forphysicians/medicalorders/Ref%20-%20Adult%20Sliding%20Scale%20for%20Insulin%20Aspart.pdf
You can also look into basal-bolus regime. Under this approach you work out a carb-insulin ratio and you dose then based on how many carbs you eat. You can also work out correction ratios. Ie. how much 1 unit insulin will drop your blood sugar. This will be much more accurate in terms of managing blood sugars than sliding scale which is more about correction after the fact.
