How to use
Choose a category, select From and To units, then type a value. Results update instantly. Swap reverses units. Copy copies the result.
Education included
Each category shows a plain-language explanation, a common formula and where you'll see it in real life (labs, vitals, nutrition and fitness).
Important note
This page converts units only. It does not provide diagnosis. Always use your lab's reference ranges and your clinician's guidance.
Interactive Converter
Some categories are "education mode" because real-world units vary by test method. The panel explains what to look for on your lab report.
Category explanation
Blood Glucose
Blood glucose measures the amount of sugar in the blood at a moment in time.
Base unit: mmol/L
Plain language
US labs commonly use mg/dL. Many countries use mmol/L.
Common formula
mmol/L = mg/dL ÷ 18.0182 (often rounded ÷18)
Real world uses
Diabetes monitoring, fasting glucose results.
Tip: You can type commas (like 12,500). The converter reads it as 12500.

Understanding Unit Systems in Medicine
Medical units come from different systems and conventions. Here's why conversions matter.
Mass-Based Units (mg/dL, g/L)
Measure the actual mass of a substance per volume. Common in the US. Glucose, cholesterol, and hemoglobin often use these.
Example: 100 mg/dL means 100 milligrams per deciliter of blood.
Molar Units (mmol/L, µmol/L)
Count the number of molecules (moles) per volume. Common internationally. Requires knowing the substance's molecular weight.
Example: 5 mmol/L glucose = 5 moles per liter of blood.
Why Conversion Factors Vary
Different substances have different molecular weights. Glucose (MW ≈ 180) and triglycerides (MW ≈ 885) use different factors.
Formula: mmol/L = (mg/dL) × 10 ÷ Molecular Weight
Regional Preferences
The US typically uses mass-based units. Many other countries prefer molar units. Always check your lab report.
Tip: Your lab report will show which units they use and their reference ranges.
FAQ
Is this a medical diagnosis tool?
No. This page converts units and explains what they mean. It does not diagnose conditions or replace medical advice. Always follow your clinician's guidance and your lab's reference ranges.
Why do lab conversion factors change by test?
Many conversions between mass units (mg/dL) and molar units (mmol/L) depend on molecular weight, so glucose and triglycerides use different factors. Always confirm with your lab report.
Why are Vision and Hearing included?
Vision and hearing results often use reference-based scales (example: dB HL or visual acuity ratios), which are educational topics more than strict unit conversions. The education panel helps explain what you're seeing.
What is the difference between mg/dL and mmol/L?
mg/dL measures mass per deciliter (US standard). mmol/L measures moles per liter (international standard). To convert, you need the substance's molecular weight. For glucose: mmol/L = mg/dL ÷ 18.0182.
Should I use these reference ranges for my own results?
These are typical ranges, but YOUR lab may have different reference ranges based on their methods and population. Always use the ranges printed on YOUR lab report and discuss results with your doctor.
