Frequently Asked Questions

What is the formula between mg/dL and mmol/L?
For glucose, mmol/L = mg/dL ÷ 18.0182 and mg/dL = mmol/L × 18.0182. Clinical practice often rounds this factor to 18.
Why do some countries use mmol/L while others use mg/dL?
Different regions adopted different lab standards. Australian pathology labs primarily use mmol/L, whereas US medical reports typically use mg/dL.
Can I use this for CGM and fingerstick values?
Yes. The conversion is unit-based only, so it works for both CGM data (like Libre or Dexcom) and standard fingerstick meter readings.
Does this tool diagnose diabetes?
No. It only converts units. Diagnosis must be made by a qualified healthcare professional using proper clinical criteria.
How do mg/L and g/L relate to mg/dL?
1 mg/dL equals 10 mg/L and 0.01 g/L. These are direct concentration unit relationships.
