I found this lingering on my phone today. I took it last week when we had a cold snap. These temperatures are in C, and trust me - when this little device showed a 'feels like' temperature of -20C, it was being optimistic. By all accounts it was closer to -30C with the wind chill. Things have warmed up a bit now though and we are approaching the time of year when I can go skiing in the morning then come down and ride the motorbike in the afternoon.
