mmol/L to mg/dLmmol/L → mg/dL
1 mmol/L = 18.016 mg/dL · 1 mg/dL = 0.0555062 mmol/L
Formula
mg/dL = mmol/L × 18.016
Example: 7 mmol/L = 7 × 18.016 = 126.112 mg/dL
These units differ only by a fixed factor: multiply by it to convert, divide to go back. The factors are exact international definitions (for example 1 inch = 2.54 cm exactly); results are rounded only for display.

Questions
How many mg/dL are in 1 mmol/L?
1 mmol/L = 18.016 mg/dL.
How many mmol/L are in 1 mg/dL?
1 mg/dL = 0.0555062 mmol/L.
What is 5.6 mmol/L in mg/dL?
About 101 mg/dL: 5.6 × 18.016 ≈ 100.9.
Why is the factor 18?
Glucose weighs about 180.16 g/mol, so 1 mmol/L = 180.16 mg/L = 18.016 mg/dL. The factor applies to glucose only; cholesterol and other tests use different ones.
