Unfortunately it doesn't make any sense with rational measurement units (kilograms an centimeters) :
Please enter your current weight > 87 Please enter your waist girth (measured at the umbilicus) > 98 Your Total Body Fat % is 350.74% This indicates that you are Obese. Extra: Your weight without any fat = -218.146
I fail to understand what the calculations are about to apply proper conversion.
