Calcium Converter (mg/dL ↔ mmol/L)
Convert serum calcium between conventional and SI units with the 4.008 factor.
Anchors: 9.5 mg/dL = 2.37 mmol/L (mid-normal), normal range ~8.5–10.5 mg/dL (2.12–2.62 mmol/L). Remember total calcium needs albumin correction — low albumin makes total calcium read falsely low (see the corrected-calcium tool). Ionised calcium is a separate measurement with its own units.
