There are two units of blood glucose level, one is milligrams per deciliter (mg/dl), which is the old unit; the other is millimoles/liter (mmol/L), which is the new unit.
Although the new system of units is now advocated, the old system of units is still in use in a certain range. Therefore, it is necessary to know how to convert between the two. The conversion formula for the two units is: mg/dl÷18=mmol/L; mmol/L×18=mg/dl.
For example: when 120mg/dl is converted into a value in mmol/L, it needs to be divided by 18, that is, 120mg/dl÷18=6.67mmol/L; when 6.67mmol/L is converted into a value in mg/dl, Need to be multiplied by 18, that is, 6.67mmol/L×18=120mg/dl.
