Units used for measuring of glucose values

Units used to measure blood or interstitial fluid glucose values depend on the country. Basically, 2 systems are used:

  • mg/dl in the United States of America, Austria, Belgium, Germany and some other countries;
  • mmol/l according to SI standard in rest of the world.

    The following conversion rule and table can be used if conversion between units is needed:
           1 mmol/l = 18 mg/dl      {Units 1}

    Tab. Units 1.    Conversion between mmol/l and mg/dl

    To convert from mmol/l to mg/dl, locate the integral part of the glucose value in the left (orange) column and the decimal part of glucose value in the top (orange) row of the table. The value in mg/dl is then found in the cell to the right of integral and below the decimal part of value in mmol/l as shown below.

    This shows that the value 7.8 mmol/l is equal to 140 mg/dl.

    To convert from mg/dl to mmol/l, locate the value in mg/dl in a white cell of the table. The integral part of value in mmol/l is then found in the orange column to the left of the cell and the decimal part of value in mmol/l is in the orange row above the cell.

    So, the value 77 mg/dl is equal to 4.3 mmol/l.
