Mmol/L to mg/dl Formula

The following formulas are used to convert between mmol/L and mg/dl:

mg/dl = 18.018 × mmol/L
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

  1. Enter mmol/L value: Input the millimoles per liter value to convert to mg/dl.
  2. Enter mg/dl value: Input the milligrams per deciliter value to convert to mmol/L.
  3. Click Calculate: The calculator will automatically convert to the other unit.
  4. 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.
