Blood Sugar Unit Converter
Different countries use different unit to measure blood sugar, so depending on where the publication is from, units may be unrecognizable. For example, in Canada we use mmol/L and in the USA they use MG/DL. Here is a handy calculator that we developed that will convert units quickly.
The corresponding chart is a quick comparison of numbers in the range from low to high.
Conversion factor: 1 mmol/L = 18.0182 mg/dL.
Zones shown are general reference points (commonly cited: <54 severe low, <70 low, 70–180 in range, >180 high, >250 very high).
This chart is for quick orientation only and is not medical advice. Always follow the targets set by your own care team.
