HbA1c and BG Unit Converter

  • HbA1c

    • DCCT

      % (Percent)

    • IFCC

      mmol/mol

  • Average Blood Glucose

    • Milligram per decilitre

      mg/dl

    • Millimole per litre

      mmol/l

Info

Following conversion formula1 is used: 

IFCC = (DCCT - 2.15) * 10.929

This is an approximation for conversion based on what I understand.

Additionally, an approximation of Average Blood Glucose based on DCCT HbA1c value are calculated using following formula:

Average Blood Glucose (mg/dl) = (A1C * 28.7) - 46.7
Average Blood Glucose (mmol/l) = (A1C * 1.59) - 2.04

Finally, entering value in one of the unit fields will also provide conversion to other unit using the formula as well as provide HbA1c values assuming the provided value is average BG measure in given unit:

BG in mg/dl = BG in mmol/l * 18
