Dear Erin

 

My First Edition Mechanical Engineering Handbook (1916) from McMillian has a 
section on wire sizes used for telegraphy. Given the specialised nature of 
their need to hold wires up in the air with wooden poles, the wire sizes are 
given in units of 'Ohms per ton-mile'.

 

I think that qualifies as 'non-standard', right?  :)

I'm delighted to have stove reports in all units, including non-standard ones 
(if you include some conversion information).  We do need some precision and 
standards, but conversion between units isn't too difficult as long as we're 
doing our best to accurately measure in the first place. I'd rather have 
everyone reporting in the units they are comfortable and confident with, and 
then doing poor conversions or worse - not reporting in the first place.
