Height & Health Context
At 128 pounds (58.06 kg), BMI moves a long way with height, so the conversion alone cannot say what the weight means for you. The table runs from 25.1 at 5ft 0in down to 16.4 at 6ft 2in. At 5ft 6in the figure is 20.6, and at 6ft 0in it is 17.3. BMI is a screening measure, not a diagnosis, and it leaves out muscle, frame and lifestyle entirely.
Most bathroom scales only show one decimal, so 128 lbs (58.0598 kg) will display as 58.1 kg. That is not an error, it is the display rounding the true figure up. I log the full 58.06 in my own records and read the on-screen 58.1 as the same weight. If your scale jumps between 58.0 and 58.1 on consecutive mornings, that is normal display rounding around the true value, not real weight change.
