I've posted about this somewhere before, but here it is again! Note the cheat sheet.. C & actual F.

Why would an old Texan, who has used Fahrenheit all his life, start using Celsius??

Not 100% sure, but I think the software in all 2-digit temperature measuring devices, that are switchable between F&C, is based on C, and perform a rough conversion when set to display in F..

Some of these devices (like the IR remote thermostat shown above) increment 1 deg when in C mode,
but in 2 deg when in F mode.. (Meaning a loss of Fahrenheit resolution).

Since my Sanyo remotes are C based, and only displays F setpoint temps
in even numbers, it's very inaccurate around the normal comfort zone..

Here's a little experiment I did.. First, I incremented the setpoint by 1 C, and then switched to F and read out the F setpoint..

C___F
18 64
19 66
20 68
21 70
22 72
23 72
24 74

Don't you just love the conversion of both 22C and 23C to 72F?? Yeah, they rounded up, and then rounded down..
So, I feel it's more accurate just to stick with C.. That way, I'll know which 72, that I'm really using..
