Surprised to read on another thread that some are still using that antiquated measure of temperature favoured by the Yanks. A poll beckons...

While you're at it, you might ask how people cope with recipes in British newspapers, how do they quickly convert, say, 23.5 grams of milk to something for which they have a measure; cups, tablespoons, wheel barrows, whatever.

you can't help using a combination in this country. My oven only works in F, when English cookbooks reference only C. My fridge has a digital readout in F only. The hot water heater also has set-points calibrated in F. Warm weather temps are more often expressed in F; sub-zero temps in C. If you travel to the States you've got to be able to think in F.

I tend to work in C and do an approximate conversion working from known fixed points - for air temps the convenient ones to remember are 16=61 and 28=82, for ovens 200=400, and so on.

For temps weather wise, strictly celsius...fahrenheit seems antiquated and distinctly american to my ears/eyes.

Cooking wise: our stove is in fahrenheit only but for measures of both liquid and non-liquid items I only think in grams/ml. Cups, quarts, tea spoons, table spoons etc has a similar antiquated feel to it. Working in units of 10 seems to do the trick for me.

In my job, metric is the mandated way and I've just applied that as much as possible to my non-work life...it seems like you are swimming against a strong tide by constantly referring to gallons (Petrol), fahrenheit in the weather, etc

The one that always makes me shake my head is our (electric) convection oven in France which has a temperature control calibrated in gas marks.

Fortunately/unfortunately, all my appliances use C. I was taught to use metric in school and I have continued to do so ever since.

I have no need to convert to F on a day to day basis and, if I am travelling in the US, I see no need to use F. The difference between 20 and 25 C would affect me as much as the difference between the F equivalent would.

If I am too cold, I put clothes on; if I am too hot, I remove some, irrespective of what the mercury says.

Mostly Fahrenheit as that is what I grew up with and learned in school and used for the first 24 years of my life.

Celsius still doesn't bring an instant recognition for me, so 36C wont instantly equate being hot in my mind like 96F would.

In school they did try and teach metric a bit in school, but can't say I learned anything..

Celsius or Kelvin all the way for me.
for some reason I can cope with high temps in Faherenheit (I know 100 is hot weatherwise) but can't visualize what 30 degrees F might be (cold , freezing , brass monkeys?)

After years of teaching physics and drumming into my students that we use Kilograms , Metres and Kelvin all the way , I now find myself contemplating an aviation equation that involves Celsius, Feet and Inches of Mercury

Fahrenheit or Celsius with a bit of Kelvin thrown in for good measure.

I even have the conversion formulas memorised. How cool is that!

I routinely do the temperature conversions. I'm disappointed if I haven't worked it out before the roadsign neon signs switch. I can't imagine cooking in C though, that'd be a faff.

A perfect summing up.

If "today" was a warm 24 and someone told me "tomorrow" was going to be 29, the difference wouldn't mean that much to me.

But if today is in the mid 70s and I'm told tomorrow will be mid 80s, then I'll have a much better idea.

On the other hand, zero or -10 says a lot more about it being cold than being 14 or 32.

On the other hand, you know it's cold when even the F hits below 0.

When we moved here, the AC/Heating thermostat was C and that helped me adjust. The thermostat on our new system is F so now I've got used to C, I'm back on F again.

In school (late 80s/90s) in the UK we were "taught" only in celsius. Never really came across fahrenheit unless it was Michael Fish on the weather telling you the temps in both.

Here in Canada our cooker is fahrenheit. I know very roughly what the temp will be in celsius but not to any great degree of accuracy.

When I was at school celsius hadn't been invented, there were only degrees centigrade and degrees Farenheit.

Must have been the one made up by Anders Centigrade of Denmark.

My stove can be switched over to Celsius, so I did, ditto with every other appliance I can think of or device I've got. Never use Fahrenheit at all.
