If you do not wish to show conversion of US measures into SI units in the QES file, then your QES file should have this:
*.QES file wtpd Weight in US pounds ###.# htft Height in US feet # htin Height in US inches ## bmi Body Mass Index in kg/m^2 ##.#
You then make all your calculations in the CHK file to get the BMI in SI units:
*.CHK file * Definitions from Wikipedia * 1 US foot=(1200/3937) meters * 1 US inch=25.4 millimeters * 1 US pound= 453.59237 grams
wtpd MUSTENTER END
htft MUSTENTER END
htin MUSTENTER AFTER ENTRY bmi=(wtpd*0.45359237)/((htft*(1200/3937)+(htin*0.0254))^2) END END
bmi NOENTER END
and that should do it. Beware of empty fields contributing to the denominator. Should that be the case, you must make provisions in the CHK file. The above works only if there are no zeros for the two denominator variables, and not permitting any blank fields.
