Diabetes Glucose Chart – mg/dl +to mmol/L

blood drop

Living in Canada where blood glucose levels are measured in mmol/L makes it sometimes difficult when watching YouTube videos figuring out what they are talking about. In the US blood glucose is measured in mg/dl.

Whats the difference between mmol/L and mg/dL?

mmol/l stands for millimoles per litre.
A mole is a scientific unit often used to measure chemicals.

mg/dl stands for milligrams (mg) per deciliter (dL).
A milligram is one-thousandth of a gram.
A gram is about 1/30 of an ounce.
A decilitre measures fluid volume that is 1/10 liter.

Formulas to convert one to the other

  1. to calculate mmol/l from mg/dl: mmol/l = mg/dl / 18.
  2. to calculate mg/dl from mmol/l: mg/dl = 18 × mmol/l.
    1 mg/dL = 0.0555 mmol/L
