Urea Conversion Formula:
From: | To: |
Urea concentration conversion between mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter) is essential in clinical chemistry for standardizing laboratory results and facilitating international comparisons.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts mass concentration (mg/dL) to molar concentration (mmol/L) using urea's molecular weight.
Details: Urea measurement is crucial for assessing kidney function, monitoring dialysis effectiveness, and evaluating metabolic status. Standardized units allow for consistent interpretation across different healthcare settings.
Tips: Enter urea concentration in mg/dL. The value must be a positive number. The calculator will automatically convert it to mmol/L using the standard conversion formula.
Q1: Why convert urea from mg/dL to mmol/L?
A: mmol/L is the SI unit for urea concentration and is widely used in many countries. Conversion ensures consistency in medical reporting and international research.
Q2: What is the molecular weight of urea used in this calculation?
A: The calculation uses 60.06 g/mol, which is the standard molecular weight of urea (CO(NH₂)₂).
Q3: Are there different conversion factors for urea?
A: No, the conversion factor is standardized based on urea's molecular weight. The formula mmol/L = (mg/dL × 10) / 60.06 is universally accepted.
Q4: What are normal urea values in both units?
A: Normal blood urea nitrogen (BUN) is approximately 7-20 mg/dL or 2.5-7.1 mmol/L. Note that BUN and urea have different conversion factors.
Q5: Can this calculator be used for BUN conversion?
A: No, this calculator is specifically for urea. BUN conversion requires a different factor since BUN measures nitrogen content (1 mg/dL BUN = 0.357 mmol/L urea).
