Oops..you're right.

Good one...we'll agree to disagree on the pros and cons of the metric/imperial worlds.

A trip to the USA must put you at ease and you don't have to deal with the logical nature of the metric system.

I'm sure you'll be delighted to hear that on the night of the Grauniad's miscalculated winter horror tale, we experienced an Imperial Dusting of the white stuff.

Of course, I immediately thought of you.

It was expensive enough to have been a Christmas present rather than just something I needed for school.

I suspect I was also one of the last school cohorts to be formally taught how to use a slide rule.
I think you'll find that they were 4 significant figures (unless your mathematics teacher was a cheapskate or cared not a whit for precision). I used only those and a 12" slide rule all the way to A level and S level double maths.

I suppose yours was shorter?

A little over a foot accumulated on the deck over Saturday night, I wondered vaguely if that was close to the 20 centimes forecast but never troubled to do the sums. Instead we rode for a good few furlongs before making up some more 8x4 panels for the barn and settling down for a couple of pints.


"Halve it and subtract 30" was always good enough to match the two neon thermometers I passed on the way work; one in F, one in C. I'd have liked to have given the F company some business, just for having the sign, but it's an undertakers.

Fahrenheit is the imperial measure I never got a feel for.

I still use both sides of the tape measure because I quite like inches but more often than not end up confusing the sh*t out of myself because I can't remember which unit I'm using.

For everyday temps f = 2c + 30 gets you within a couple of degrees quickly. Certainly good enough for the old people that need to know.

Wouldn't it be young people who need to convert? People educated here who want to leave their subdivision and travel a bit. They'd likely want to convert the temperatures in the forecast to the only ones they know.

If by travel you mean "nip over the border to do a bit of shopping" then I suppose so. But mostly everywhere else uses celcuis.

No need to convert when the temperature hits minus 40 C or F and no need to convert the language you would use either to describe how cold it is

You're right, of course. Four-figure tables.

Godfrey & Siddons. The "other" great G&S partnership, as my maths teacher (a fan of the d'Oyly Carte company) told us. A nugget from the depths of memory...
