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 does Canada use mmol/L while the US uses mg/dL?
Canada adopted the metric Systeme International d'Unités (SI), using millimoles per litre (mmol/L). The US uses mg/dL. This tool helps bridge that gap.
Can I use this for CGM (e.g., Dexcom) and fingerstick values?
Yes. The conversion is unit-based only, so it is compatible with data from Continuous Glucose Monitors and standard fingerstick meters.
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.
