Conversion Formula:
| From: | To: |
The conversion from mmol/L to mg/dL is a common calculation in medical and scientific fields, particularly for substances like glucose, cholesterol, and other biochemical compounds. This conversion requires knowing the molecular weight of the substance being measured.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts molar concentration (mmol/L) to mass concentration (mg/dL) using the molecular weight of the substance and a conversion factor that accounts for the relationship between moles, milligrams, and deciliters.
Details: Accurate unit conversion is essential for comparing laboratory results across different measurement systems, interpreting clinical guidelines, and ensuring proper medication dosing in medical practice.
Tips: Enter the concentration in mmol/L and the molecular weight of the substance in g/mol. Common molecular weights: glucose = 180, cholesterol = 387, creatinine = 113. All values must be positive numbers.
Q1: Why is molecular weight needed for conversion?
A: Molecular weight is essential because it relates the number of molecules (moles) to their mass, allowing conversion between molar and mass concentrations.
Q2: What are common molecular weights used in medical conversions?
A: Glucose: 180 g/mol, Cholesterol: 387 g/mol, Creatinine: 113 g/mol, Urea: 60 g/mol, Sodium: 23 g/mol.
Q3: When is this conversion most commonly used?
A: Most frequently used for blood glucose measurements, lipid panels, renal function tests, and electrolyte measurements in clinical settings.
Q4: What is the 0.1 conversion factor derived from?
A: The factor 0.1 comes from converting liters to deciliters (10 dL/L) and grams to milligrams (1000 mg/g): 1000 mg/g ÷ 10 dL/L = 100, then adjusted for mmol (÷10) = 0.1.
Q5: Can this calculator be used for all substances?
A: Yes, as long as you know the correct molecular weight of the substance being measured. The formula is universal for converting mmol/L to mg/dL.
