Glucose: mg/dL ↔ mmol/L

Glucose unit conversion (international lab results).

mg/dL

= 0.00 mmol/L

mmol/L

= 0 mg/dL

Note: This uses the standard glucose factor (18.0182). Some sources round to 18.

mg/dL = mmol/L × 18.0182

mmol/L = mg/dL ÷ 18.0182

Many sources round 18.0182 to 18 for quick mental math.
