brrrrr cold! so of course it's Winter Field Day

Don't worry, we will *not* be outside for operations tomorrow and Sunday. I don't envy the folks doing antenna setup, though... :P

If anyone so inclined and with suitable gear happens to hear W9JZ on the ham bands this weekend, that's us!

For reference, it is bitterly, horribly, frakkingly cold in this region of the States right now. As in, probably -20 or worse C, and that's air temperature. I won't even try to convert wind chill; I'll only make a hash of it. I really do need to find, or preferably learn, a reliable method of degree scale conversion. Anybody know one?

I still can't get the hang of Celsius after all the time I've lived in a country that (mostly) uses it. I have a rough idea of what's a nice day and obviously I know what freezing is and all that. But if the weather app says its 7°C outside, I don't know how to dress. So I still have mine in F (where it says 45 right now, which is about 7°C) and then I know what to do.

I just type the temperatures into Google. Like at my parents' house right now it's apparently -8. If I type "-8 F in C," the first thing that pops up is just the answer in big letters: -22C, apparently.

I have a rough idea of some temperatures and what they convert to i.e. 21C is a reasonably nice day, 38C is bonkers hot, 5C or so is normal autumn or early winter, but drop too far below the freeze-thaw point and I get lost. -22C sounds about right, too - gah! That'd put it around -20C here.

Glad to know I'm not the only one who struggles with conversions.

I just don't get F I'm afraid and wouldn't know where to begin! :o)

Noooo worries. It's an odd system, and I admit it. :)

a degree C is 1.8 (9/5ths) degrees F. Freezing is 0 C and 32 F.

so to convert C to F:

multiply the C by 1.8 and add 32.

To convert F to C
subtract 32 and then divide by 1.8

You can derive the above from first principles by noting that it's 100 C from freezing to boiling, and 180 F from freezing to boiling (212-32=180). Plus the fact that freezing is 32F.

I'd never worked it out that way, or that logically. Thanks! :D

Over the years I've memorized a *lot* of conversion factors to make figuring things out easier.

One of the oddest is that a US gallon is legally defined as 231 cubic inches.
