Worked example
1.5 mg/L (middle of the reference range) = 127 nmol/L
Conversion formulas
| nmol/L | nmol/L = mg/L × 84.75 | mg/L = nmol/L × 0.0118 |
|---|---|---|
| µmol/L | µmol/L = mg/L × 0.08475 | mg/L = µmol/L × 11.8 |
| mg/dL | mg/dL = mg/L × 0.1 | mg/L = mg/dL × 10 |
| µg/dL | µg/dL = mg/L × 100 | mg/L = µg/dL × 0.01 |
| µg/L | µg/L = mg/L × 1000 | mg/L = µg/L × 0.001 |
Good to know
Beta-2 microglobulin is reported in mg/L or nmol/L. The page converts between the units only.
- nmol/L × 0.0118 = mg/L (exact factor 0.0118).
- The range shown is a guide from the named source; targets and reference ranges differ between laboratories, methods and indications, so compare with the range on your own report.
Reference range
| Unit | Adults |
|---|---|
