Mmol/L to mg/dl Calculator
Enter the mmol/L or mg/dl into the calculator to convert to the other value. This calculator can convert mmol/L to mg/dL or mg/dL to mmol/L for blood glucose concentration measurements.
Mmol/L to mg/dl Formula
The following formulas are used to convert between mmol/L and mg/dl:
mmol/L = mg/dl ÷ 18.018
Where mg/dl is milligrams per deciliter and mmol/L is millimoles per liter. These units are commonly used for glucose concentration measurements.
How to Use This Calculator
- Enter mmol/L value: Input the millimoles per liter value to convert to mg/dl.
- Enter mg/dl value: Input the milligrams per deciliter value to convert to mmol/L.
- Click Calculate: The calculator will automatically convert to the other unit.
- View Results: Both values will be displayed with the conversion method used.
Understanding Blood Glucose Units
Both mmol/L and mg/dl are units used to measure glucose concentration in blood:
- mmol/L: Millimoles per liter - commonly used in many countries including the UK, Canada, and Australia
- mg/dl: Milligrams per deciliter - commonly used in the United States
Conversion Examples
Normal Fasting Glucose
5.6 mmol/L = 100.9 mg/dl
Pre-diabetes Range
6.1 mmol/L = 109.9 mg/dl
Diabetes Threshold
7.0 mmol/L = 126.1 mg/dl
Frequently Asked Questions
How do you convert mmol/L to mg/dL?
To convert millimoles per liter to milligrams per deciliter, multiply the mmol/L value by 18.018. This conversion factor is specific to glucose measurements.
How do you convert mg/dL to mmol/L?
To convert milligrams per deciliter to millimoles per liter, divide the mg/dL value by 18.018. This gives you the equivalent glucose concentration in mmol/L.
Why is the conversion factor 18.018?
The conversion factor 18.018 is derived from the molecular weight of glucose (180.156 g/mol) and the unit conversions between liters/deciliters and grams/milligrams.
Which unit system should I use?
The choice depends on your location and healthcare system. mmol/L is used in most countries worldwide, while mg/dl is primarily used in the United States. Always follow your healthcare provider's preferred unit system.
