Sorry if this sounds a bit strange. I do not have a set of scales in my house - just judge how my clothes fit etc to see if I am gaining weight etc. But now I have to fill in a form with my weight on. Last time I went to the doctors I was weighed - a few weeks ago, but I can't remember the weight as it was in kg which didn't mean a lot to me. I do know that I am 5'8" and she said my BMI was 27. So - can anyone work out what weight I am from this??
