Health3 Biomarker Unit Converter

About

Your lab report says 5.5 mmol/L but every reference you find uses mg/dL. Sound familiar?

Health3 Biomarker Unit Converter instantly converts between medical measurement units for 182 blood test biomarkers - covering 935 unit combinations. No signup, no data collection, works completely offline.

HOW IT WORKS
1. Click the extension icon in your toolbar
2. Search for your biomarker (e.g., Vitamin D, Glucose, Cholesterol)
3. Enter your value and select the source and target units
4. Get an instant, medically-accurate conversion

WHAT YOU CAN CONVERT
• Mass to molar: mg/dL ↔ mmol/L, ng/mL ↔ nmol/L, pg/mL ↔ pmol/L
• Equivalent units: mEq/L ↔ mmol/L (electrolytes)
• Enzymatic activity: U/L ↔ µkat/L ↔ nkat/L
• Cell counts: ×10⁹/L ↔ cells/µL ↔ G/L ↔ k/µL
• HbA1c: % ↔ mmol/mol ↔ fraction
• Insulin: µIU/mL ↔ pmol/L
• Clearance: mL/min/1.73m² ↔ mL/s/1.73m²
• And hundreds more...

REFERENCE RANGES INCLUDED
Each conversion shows all available reference ranges from clinical sources - transparently labeled by sex, age group, and source publication. We show the full picture so you can find the range that applies to you.

Sources include Tietz Textbook of Laboratory Medicine, StatPearls, Mosby's Diagnostic Reference, and peer-reviewed publications.
