To convert mmol/l of glucose to mg/dl, multiply by 18.
To convert mg/dl of glucose to mmol/l, divide by 18 or multiply by 0.055.

The latest trend in meal planning for children with diabetes is carbohydrate counting. CHO counting can be used with prescribed carbohydrate ranges for each meal and snack. Alternatively, patients can be given a CHO/insulin ratio, so that their insulin dose at each meal can be adjusted to the CHO content of their anticipated meal in addition to their pre-prandial blood glucose level.
The good news is that CHO counting and the use of CHO/insulin ratios allow more precision and greater flexibility in eating and lifestyle.
How do you determine a ratio and blood sugar correction factor?
Rules
– 1500 Rule
Blood Sugar Correction Factor (1500: TDD)
1500 divided by TDD = # of points (mg/dl) blood sugar will be lowered by 1 unit of REGULAR insulin
– 1700, 1800, 2000 Rule
Correction Factor
Same principle as above – however for RAPID ACTING insulin
Depends on proportion of basal to bolus dose
– 500 Rule
Insulin to Carb Ratio (500: TDD)
500 divided by the TDD
For RAPID ACTING insulin
Calculating a Dose
Insulin to carb ratio = 1 unit per 15 gm carb
BG correction = 1 unit per 50 over 150
Carb component: 60gm ÷15 = 4 units
Blood sugar correction: 250 -150 = 100 100÷50 = 2 units
Total Dose = 4 units + 2 units = 6 units
“Smart Pumps”- Do the math for you!
Calculating a Correction Dose
we usually talk in approximations anyway.
mmol/l mg/dl interpretation
—— —– ————–
2.0 ———35 extremely low, danger of unconciousness
3.0 ———55 low, marginal insulin reaction
4.0 ———75 slightly low, first symptoms of lethargy etc.
5.5 ———100 mecca
5 – 6 ——–90-110 normal preprandial in nondiabetics
8.0 ———150 normal postprandial in nondiabetics
10.0 ——–180 maximum postprandial in nondiabetics
11.0 ——–200
15.0 ——–270 a little high to very high depending on patient
16.5 ——–300
20.0 ——- 360 getting up there
22 ———-400 max mg/dl for some meters and strips
33 ———-600 high danger of severe electrolyte imbalance
Preprandial = before meal
Postprandial = after meal
