Here at BY all our compartment temp indications are in degrees C, this includes the A/C temps on the Eicas ECS/MSG page, such as the pack out temp.

Our overheads are in F, but I seem to recall a few of the parameters on the maintenance pages are on C. I'm sure it's just a software issue.

Customer Option set by the vendor. The option is set inside the Compartment Temp Ind Panel.

Ref WDM 21-65-01. Option is et by either opening or shorting pins 12 and 13 on connector D3578 at the Compartment Temp Ind Panel.
An open circuit btwn pins 12-13 would give you °C and jumping the 2 would give you °F.

I should have said AT the panel.

IIRC an informal standard for US delivered aircraft was ^oF for passenger spaces and ^oC for ducts and packs where temperatures were of more interest to engineers.

Exceptions to this probably outnumber confirmations.
