Both calculators run independently — change the inputs on either side to compare results.

Corrected Calcium Calculator

Adjusts a patient's measured serum calcium for low albumin levels, revealing the true physiologically active calcium concentration. Used in labs and clinical settings when hypoalbuminemia may mask true hypercalcemia or hypocalcemia.

Body Surface Area Calculator

Calculate body surface area (BSA) in m² using the Mosteller, Du Bois or Haycock formula from your weight and height. Clinicians use BSA to dose chemotherapy, normalise cardiac index and estimate burn coverage.
