Calculating the doseage for insulin is hard for some. Actually it is reallly simple:

its:
.02U X KG of body weight_ this is for a normal weighted person. someone who is not considered obese or 50 pounds or more overweight.

so first we have to figure out what a KG is
thats 2.2 pounds. So lets use my weight

220 pounds divided by 2.2 pounds is 100 kilos ( KG)

so then because I am obese we have to use .05 units.
So we then multiply 100 X .05 =50 Units of insulin.

See...
now 50 units of insulin is adjusted for the N, or Long acting insulin.
