Yeah, as a nation we like to exaggerate stuff so if it's hot people will use farenheit and say "Wow, it must be 90 degrees out there" but in the winter they'll use celsius and say "it's only 2 degrees outside, we might get snow".
Anyone British here can back that up, we mix and match when it suits us
Before complaining about how COLD it is, maybe they should try living somewhere that a colder temperature winds up being colder in F than C for a change (obviously, in the - zone)! Ha-ha!
Oh wait. Nevermind, the British do not have the concept of indoor heating nailed down yet...
