The simplest one, which I use in a computer program I wrote
(which runs in real time in hospital cardiac operating rooms)
is:

FUNCTION bsa
PARAMETERS kg, cm
rtnval =ROUND(.007184 * cm^0.725 * kg^0.425,2)
RETURN rtnval

i.e.

0.007184
x height in cm raised to 0.725 power
x weight in kg raised to 0.425 power

rounded to 2 decimal places. There's another with LOG in the
expression which I'm not finding at the moment (research project
for extra credit?).

A quick net search ("Body Surface Area" entered in Alta Vista)
yields these additional resources:
