Conversion formulas
| g/L | g/L = mmol/L × 0.02431 | mmol/L = g/L × 41.14 |
|---|---|---|
| mEq/L | mEq/L = mmol/L × 2 | mmol/L = mEq/L × 0.5 |
| mg/dL | mg/dL = mmol/L × 2.431 | mmol/L = mg/dL × 0.4114 |
| mg/L | mg/L = mmol/L × 24.31 | mmol/L = mg/L × 0.04114 |
| µmol/L | µmol/L = mmol/L × 1000 | mmol/L = µmol/L × 0.001 |
| µg/dL | µg/dL = mmol/L × 2431 | mmol/L = µg/dL × 0.0004114 |
