I am Canadian, have type 2 diabetes and my normal blood sugars are 4-7. I notice americans use 100s (ex. 105 or 125). What is the normal range when using this model?

You’re correct. In the U.S., blood glucose levels are measured in milligrams per deciliter, abbreviated as ” mg/dl”. To convert mg/dl to millimoles per liter (mmol/l), which is the unit of measurement used in Canada and elsewhere, divide by 18. For example, a blood glucose of 120 mg/dl divided by 18 equals 6.67, rounded up to 7. In the U.S., the pre-meal target blood glucose range for most people with diabetes is 70-130 mg/dl, which is equal to 4-7 mmol/l. Two hours after a meal, the blood glucose goal is less than 180 mg/dl, or less than 10 mmol/l. You can convert from mmol/l to mg/dl by dividing by 18. And to make it easier, you can find on-line conversion calculators on sites such as and
