The conversion from mg/dL (milligrams per deciliter) to mmol/L (millimoles per liter) is a common unit conversion used in medical and scientific fields, particularly for measuring concentrations of substances in blood and other biological fluids.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass concentration to molar concentration by accounting for the molecular weight of the substance and adjusting for the different volume units (dL to L).
Details: Accurate unit conversion is essential for medical diagnosis, laboratory reporting, international standardization, and proper interpretation of test results across different measurement systems.
Tips: Enter the concentration value in mg/dL and the molar mass of the substance in g/mol. Both values must be positive numbers. Common molar masses: Glucose = 180.16, Cholesterol = 386.65, Creatinine = 113.12.
Q1: Why is the conversion factor 10 used?
A: The factor 10 accounts for the conversion from deciliters (dL) to liters (L), since 1 L = 10 dL.
Q2: What is the difference between mg/dL and mmol/L?
A: mg/dL measures mass concentration while mmol/L measures molar concentration, which accounts for the molecular weight of the substance.
Q3: When is this conversion typically used?
A: Commonly used for blood glucose, cholesterol, creatinine, and other biochemical measurements where different countries use different reporting units.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact when the correct molar mass is used. Accuracy depends on using the appropriate molecular weight for the specific substance.
Q5: Can this calculator be used for all substances?
A: Yes, as long as you know the correct molar mass of the substance you're converting.
