Worked example
0.935 mmol/L (middle of the reference range) = 1.87 mEq/L
Conversion formulas
| 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 |
Good to know
Magnesium in cerebrospinal fluid is reported in mmol/L, mg/dL or mEq/L.
- mEq/L = mmol/L × 2; 1 mmol/L = 2.43 mg/dL.
- Published reference ranges differ considerably (for example 0.65-1.22 and 1.2-1.5 mmol/L), so treat the range shown as an orientation value.
Reference range
| Unit | Adults |
|---|---|
| mmol/L | 0.65 – 1.22 |
| mEq/L | 1.3 – 2.44 |
| mg/dL | 1.58 – 2.966 |
| mg/L | 15.8 – 29.66 |
| µmol/L | 650 – 1220 |
| µg/dL | 1580 – 2966 |

Note from the source: 0.65-1.22 mmol/L (96th-percentile limits, 102 samples, atomic absorption; study from 1972). CSF magnesium varies more than serum magnesium; other references quote higher values
