Title: Re: [USMA:34984] Re: Metric converter web site?

Dear Pat,
Thanks for your message. It happened in the
beginning of the 19th century, of course. I have seen
numerous
arithmetic school books in Ireland, but I can
inform you that they spent hardly or no time at all at converting. I am also convinced that 'conversion' as an art of arithmetic
is the bane of metrication.
However, the Irish school
books often carried another grievous error: wrong notation of metric
units. Too often there were notations like 1 kg 6
hg, 1 m 5 dm 4 cm 9 mm, 1 km 800 m etc. Something pupils have to
unlearn in secondary education.
Cheers,
Han

Dear
Han,
Thanks for these insights into the early history of
metrication.
Your report on the early days in the Netherlands of the
early 18th century reminded me that most of the activities about the metric
system in Australia and in the USA during the 1970s were about metric
conversion. The school texts were, in particular, fully laden with numerous
examples converting between old pre-metric units and metric units, but worse,
there were also many examples changing from metric units to various old
pre-metric measures.
Over many years, I have collected books intended
for helping people 'convert' to the metric system. Most of these have
extensive sections detailing how to do metric
conversions.
Cheers,
Pat Naughtin
