Conversion Formula:
From: | To: |
This calculator converts alcohol concentration between micromoles per liter (μmol/L) and micrograms per deciliter (mcg/dL). These units are commonly used in clinical and forensic settings to measure blood alcohol concentration.
The calculator uses the conversion formula:
Where:
Explanation: The formula accounts for the molecular weight of ethanol and the volume conversion between liters and deciliters.
Details: Different countries and medical institutions use different units for reporting blood alcohol concentrations. Converting between these units is essential for accurate interpretation of results.
Tips: Enter the alcohol concentration in μmol/L. The calculator will automatically compute the equivalent value in mcg/dL.
Q1: Why are there different units for alcohol concentration?
A: Different regions and scientific disciplines have developed different conventions for reporting concentrations. μmol/L is more common in clinical chemistry, while mcg/dL is often used in forensic settings.
Q2: What is the molecular weight of ethanol?
A: The molecular weight of ethanol (C₂H₅OH) is 46.07 g/mol, which is used in the conversion calculation.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact when using the correct molecular weight. However, actual measurements may have analytical variability.
Q4: Can this be used for other substances?
A: No, this specific conversion is only valid for ethanol. Other substances would require using their specific molecular weights.
Q5: What are typical blood alcohol concentrations?
A: Legal limits vary by country but are typically around 17-22 μmol/L (80-100 mcg/dL). Severe intoxication may occur at levels above 43 μmol/L (200 mcg/dL).
