1. What is BUN Conversion?

BUN (Blood Urea Nitrogen) conversion between mmol/L and mg/dL is essential for medical professionals working with different measurement systems. This calculator converts BUN values from mmol/L (commonly used internationally) to mg/dL (commonly used in the United States).

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ \text{BUN (mg/dL)} = \text{BUN (mmol/L)} \times 2.801 \]

Where:

\( \text{BUN (mmol/L)} \) — Blood Urea Nitrogen concentration in millimoles per liter
\( 2.801 \) — Conversion factor (molecular weight of nitrogen × 10 ÷ molecular weight of urea)
\( \text{BUN (mg/dL)} \) — Blood Urea Nitrogen concentration in milligrams per deciliter

Explanation: The conversion factor 2.801 is derived from the molecular weights of urea and nitrogen, allowing accurate conversion between the two measurement units.

3. Importance of BUN Measurement

Details: BUN is an important clinical marker for kidney function assessment. Accurate conversion between measurement units is crucial for international medical communication, research collaboration, and proper interpretation of laboratory results across different healthcare systems.

4. Using the Calculator

Tips: Enter the BUN value in mmol/L. The calculator will automatically compute and display the equivalent value in mg/dL. Ensure the input value is valid (non-negative number).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 2.801?
A: The factor 2.801 comes from the molecular weight calculation: (28.01 g/mol for N₂) × 10 ÷ (60.06 g/mol for urea) = 2.801.

Q2: What are normal BUN values?
A: Normal BUN levels are typically 7-20 mg/dL (2.5-7.1 mmol/L), but ranges may vary slightly between laboratories.

Q3: When is BUN conversion needed?
A: Conversion is needed when comparing international research studies, interpreting lab results from different countries, or when medical protocols use different measurement units.

Q4: Are there limitations to this conversion?
A: The conversion is mathematically precise, but clinical interpretation should consider patient factors like hydration status, liver function, and protein intake.

Q5: Can I convert mg/dL to mmol/L with this calculator?
A: This calculator specifically converts from mmol/L to mg/dL. For reverse conversion, use the formula: BUN (mmol/L) = BUN (mg/dL) ÷ 2.801.
