Wow Yikes! I think there is an option (something to click in the circle) to change it to measure in pounds. I just did mine this morning and I know I entered weight in pounds. HTH.
Nancy, there is a way to change to kgs to pounds somewhere. I've been looking for it and can not find it. Hopefully someone else will chime in.
Also, there must be a bug for the goals portion that shows up on the profile page. Because mine shows my weight at >150 and my BMI at 35 or so I weigh 128 and my BMI is around 20 Whats up with that?
