Unit Conversion
Choose an analyte, conversion direction, and enter the value to convert between mmol/L and mg/dL using standardized molecular weight factors.
Plasma glucose; mmol/L × 18.02 = mg/dL
Converted value
100.90 mg/dL
How to Use This Calculator
Select the analyte
Choose the lab analyte you need to convert. Factors differ because molecular weights vary.
Set the conversion direction
Decide whether you are converting from mmol/L to mg/dL or in the reverse direction.
Enter the numeric value
Input the laboratory result. The converter applies analyte-specific factors to output the converted value instantly.
Formula
mg/dL = mmol/L × Conversion factor
mmol/L = mg/dL ÷ Conversion factor
The conversion factor equals molecular weight ÷ 10 for each analyte (e.g., glucose 180.18 ÷ 10 ≈ 18.02).
Full Description
Laboratory units vary globally. SI units (mmol/L) report molar concentration, whereas conventional units (mg/dL) reflect mass per volume. Accurate conversion requires analyte-specific molecular weights. This calculator streamlines everyday transitions between SI and traditional units, ensuring consistency in clinical communication and decision-making.
Frequently Asked Questions
Why do factors differ among analytes?
Conversion depends on molecular weight. Higher molecular weights require larger factors to convert mmol/L to mg/dL.
Can I add custom analytes?
Currently preset analytes are supported. Extend the list by adding molecular weight-based factors in the code if needed.
Should I round results?
Laboratories typically report to one or two decimal places. Adjust rounding to match your documentation standards.
Does temperature affect conversion?
No. Conversions rely on molecular weight, which is independent of temperature within clinical ranges.
