I was born in 1975 and decimelisation happened in 1974.
My daughter (who was born in 2009) is very small for her age. We have had the health visitor come out to weigh her because she is on 0.4th centile and I find it really hard to get to clinic.
I have a lovely health visitor who converts her weight (in kg that I understand) to lbs (which is gobbly gook to me!).
My health visitor is also concerned about my weight and asked me what I weighed. I told her that I was 169cm tall and weighed 54kg. Her next question was "What that in stone?" I had to go and get a calcuator to convert it for her.
My health visitor is very talented at job. I can't fault her in any way. It does seem weird that she uses imperial units for her job. Especially as she trained after decimelisation.
