    Body fat % is body fat %, BMI is the ratio of weight to height. BMI is a flawed calculation and only good for very general estimates.

    Course, scales that do electrical impedance (most home scales use this method) can have a rather large margin for error, I wouldn't put much stock in a 1% change from a scale. They can vary based on how hydrated you are greatly.
