Being a border city has advantages and disadvantages, one disadvantage is having to always refer to imperial and metric units against your will. Sometimes you end up with a strange mix, I usually refer to temperature in the summer in F and temperature in the winter seems to make more sense in C.
If you know anyone in the US and have ever had a conversation about blood sugar, it may surprise you to hear how happy they are to have their fasting sugars below 100 (which in Canada would equate to about 5.5), or them to hear you explain how you had a SLIGHT low of 3.5 (which in the US would actually equate to 63).
The world standard unit for measuring glucose in blood is mmol/l, it is the measurement of the number of (or concentration of) glucose molecules (moles) per liter of blood.
Mg/dl is primarily used in the US and is a measurement of the weight of glucose in milligrams (1/1000 of 1 gram) per deciliter (1/10 of 1 liter) of blood.
The mole is expressed by using a standard number of molecules of a substance, and the weight (mass) of molecules varies among substances, therefore 1 mole does not always equal the same weight.
See below for the generally accepted conversion between mmol/l and mg/dl for various aspects of blood work:
To convert blood sugar from mmol/l to mg/dl multiply by 18
To convert blood sugar from mg/dl to mmol/l divide by 18
To convert cholesterol from mmol/l to mg/dl multiply by 39
To convert cholesterol from mg/dl to mmol/l divide by 39
To convert triglycerides from mmol/l to mg/dl multiply by 89
To convert triglycerides from mg/dl to mmol/l divide by 89
It also sounds worse to hear your high sugar numbers in US style, when I was diagnosed in 2009 I had a fasting glucose of 19.2 . . . it definitely would have been much more dramatic if the nurse had gasped and exclaimed ”your blood sugar is almost 350!” . . . they should do that to make the newly diagnosed pay attention I think.
