Myoglobin Unit Converter
Myoglobin (Mb) is a small, oxygen-binding protein found exclusively in the cytoplasm of **cardiac muscle** and **skeletal muscle** cells. It serves as a reservoir for oxygen within muscle tissue.
Clinically, Myoglobin is used as an early, though non-specific, marker of **muscle injury** (e.g., rhabdomyolysis or severe trauma). While historically used to diagnose acute myocardial infarction (MI), it is now largely replaced by cardiac-specific **Troponin**. High levels, particularly in rhabdomyolysis, pose a high risk for **Acute Kidney Injury (AKI)**. This converter facilitates switching between the SI molar unit (nmol/L) and mass units (ng/mL, µg/L).
SI Units / Mass
RecommendedMicrograms per liter (Numerically µg/L = ng/mL).
Molar / Mass Equivalents
Clinical Context
Reference Range (Serum): Typically 0 – 85 ng/mL (0 – 85 µg/L).
In severe muscle injury (rhabdomyolysis), Myoglobin levels can reach thousands of ng/mL. Levels above 1,000 ng/mL indicate a high risk for renal complications due to myoglobin precipitation in renal tubules. The conversion factors are based on molecular weight (MW) 16,700 g/mol:
• Mass to Molar: 1 ng/mL ≈ 59.88 nmol/L
1 ng/mL = 1 µg/L.

How to Use This Converter
Follow these steps to get accurate clinical conversions instantly.
Enter Values
Input your laboratory results into the corresponding unit field (e.g., ng/mL). You can use either dot or comma decimals.
Automatic Conversion
The calculator works in real-time. Conversions cover mass (µg/L) and molar (nmol/L) units.
Verify Units
Check the SI Units section. For Myoglobin, ng/mL is numerically identical to µg/L.
Reset

Frequently Asked Questions & Tips
Yes. 1 ng/mL = 1 µg/L.
Myoglobin is released from *any* skeletal muscle damage, making it non-specific. Cardiac Troponin is much more specific to the heart muscle.
