My weigh in is on a Tuesday. My pharmasist and his assistant (who normally weighs me) are off on hols for 2 weeks, so I don't know who'll be doing it tomorrow. Like you I have some scales issues at the pharmacy - their scales is set in kg and I'm depending on the assistant to calculate the conversion accurately. Sometimes I weigh different on theirs to mine. Mine is electronic like theirs but set for lbs & stones. I sometimes feel there are "maths conversion issues" going on. But I always go on mine. Tomorrow, I'm dreading because I've seen who is replacing the assistant while she's away & I know there will be conversion issues definitely. But maybe I'm just looking at the worst possible scenario, she might be fine.
