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. The US commonly uses mg/dL, while many countries in Europe and Asia commonly use mmol/L.
Can I use this for CGM and fingerstick values?
Yes. The conversion is unit-based only, so it can be used for both CGM data and 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.
