From Ottawa, Ontario, Canada:

We have a daughter diagnosed with diabetes a bit over a year ago. Recently we been using the chat lines on your web site and talking to other parents and children in the United States about blood sugar levels. We measure blood sugar levels in MM but have learned that a different measurement is used in the United States. Can you provide me with (1) an understanding of the measurement system in the United States and (2) the manner of converting a reading in MM to the US equivalent?


The measurement of blood sugar (and other medical lab measurements) in the USA is quoted as being in mg/dl (milligrams per deciliter). The rest of the world uses mmol/l (millimoles per liter). Why the USA insists on being backwards, still using miles instead of kilometers, and mg/dl instead of mmol/l, is a very long story.

Anyway, to translate from mmol/l to mg/dl, multiply (or divide, depending on which way you're going) by 18.

Example: a blood sugar of 10 mmol/l is 180 mg/dl.
