info: this thinbasic application is an update from the example I've sent some weeks ago. the new version shows both calculations for a) us_english metrics and german_european values. this BodyMassIndex example shows bmi result that's acceptable for normal human beeings and bodys without any handicaps (missing arms, legs, fingers, feet). this application uses standard bmi table from WHO organisation. this bmi calculator isn't perfect for children or very strong muscle bodys (bodybuilders). but for adults, the youth and older people up to 76-80 years old this bmi calculator should be ok.
