Recommended formula:
Surface area (Mosteller formula): <%= formatFloat(mosteller, "m²", 3) %>Other formulae (we don't recommend using those in clinical practice):
Surface area (DuBois & DuBois formula): <%= formatFloat(dubois, "m²", 3) %> Surface area (Haycock formula): <%= formatFloat(haycock, "m²", 3) %> Surface area (Gehan & George formula): <%= formatFloat(gehanGeorge, "m²", 3) %> Surface area (Boyd formula): <%= formatFloat(boyd, "m²", 3) %> [/calculator-output][/calculator]
