The alarm limits on temperature are a bit of a problem that's the why in Europe decimalisation has become a standard (well in most cases) so Deg. C is easy, litres instead of gallons, kilo instead of pounds and thank god in England we got rid of the gallon as this was different to japan & America. Although apart from temperature they are reasonably easy to convert. however, as individuals some old stick in the mud types prefer to recognise 70 Deg. F as a base for a good summer temperature (they cannot get their heads round 21 Deg. C) and as water freezes at 0 Deg. C and Boils at 100 decimal makes sense.
We have the Babylon's & Egyptians to thank for duodecimal base of 12 and 365 days a year with a last minute thought of an extra day every 4th one. In England although most things in electrical or electronic have converted to metric the hammer bashers (Mech. Eng.) still use BSP and inch etc. Anyway a percentage deviation seems the best way out in this case or perhaps the best way is for the rest of the world to convert to totally metric, then perhaps the Hubble telescope may have worked first time LOL.
Hammer Bashers = Mechanical Engineers in the UK
What do you call Electrical Engineer there? Usually Sparky in the USA.
Any others wish to chime in with other names.
