Blood Sugar Conversion Calculator

Conversion formulas

The blood glucose convertor can perform either of the transformations, be it that we start from mg/dL or mmol/L.

The calculator allows an unlimited amount of conversions and can help with transformation when glucose tests are performed under different systems.

• The mmol/L unit is the molar concentration, also known as millimolar (mM). This is equal to 18.0182 mg/dL.

1 mmol/L = 18.0182 mg/dL which means:

Value in mg/dL (mmol/L to mg/dL) = Glucose value in mmol/L x 18.0182

In the US, the miligrams per deciliter, mg/dL is preferred. This is equal to 0.0555 mmol/L.

1 mg/dL = 0.055 mmol/L which means:

Value in mmol/L (mg/dL to mmol/L) = Glucose value in mg/dL x 0.0555

About blood sugar levels

Blood sugar or blood glucose level is the amount of glucose, the primary source of energy for the body cells, present in the blood.

Glucose is regulated by a series of metabolic processes, mostly led by the hormone insulin, produced by the pancreas.

Normal glucose levels in a healthy individual (fasting values) are between 72 and 108 mg/dL which equals to 4.0 to 6.0 mmol/L.

These values are usually lower in the morning and rise during the first two hours after each meal.

Values that are pathologically high indicate hyperglicemia whilst lower than normal values indicate hypoglycaemia.

Long term hyperglycemia is associated to diabetes mellitus, heart and/or kidney disease whilst hypoglicemia may lead to lethargy, shaking, sweating, muscle weakness and impaired mental function.

The following table introduces blood glucose levels in both measurement units and their indication:
