Q. In English please in OhmMetres would be nice! Thanks :-)Graham M [last name deleted for privacy by Editor]
A. Try goodfellow on the internet. It gives all the figures (inc. resistivity) for various materials inc. constantan.J S. [last name deleted for privacy by Editor]

A. 52*10^-8 Ohm meters
I also saw the 49*10^-8 but this said it was "constantan (eureka)"

Ed. note: Your number differs by 6 percent, Nathan, so it's not a terrible correlation.

A. Found experimentally constantan resistivity to be 4.9*10^(-7) so it is correct!bob r [last name deleted for privacy by Editor]
