Covid-19 Heat Resistance

That may somewhat work in those ranges but not at -40 Celsius or Fahrenheit :canada::canada:

Luckily -40c = -40f

Strangely I can't seem to remember Chris's rule of thumb calcs so I use the numbers 5, 9 & 32 then do the sums in my head.
20C divided by 5 = 4, times 9 = 36, plus 32 = 68F.

Convert lives on my computer and gets used all the time.

There's is no rime or reason to conversion
but you were bang on!!

 

[JimS123]

This is ridiculous. Didn't y'all go to high school? What's the sense of roughing it to get an approximation?

C = (F-32)5/9

F = (C+9/5) + 32

Luckily -40c = -40f

The only thing I know is 0c is 32f..

You want a Mulligan on this one?

Nobody can do fractions. Try this one - F = C X* 1.8 + 32

*Multiply, not add.

Me - I just look at the thermometer.

yeah me too and preferably a digital one ...

And a button to convert is nice. The heck with math, I'm not in school anymore.

It was just so darn ironic when he asked if people went to high school and he posts that!

Yes, those are the EXACT conversion formula.

Very few of us need to know the exact conversion to the 3 significant figures. 'About' is good enough, so what I gave was the Q&D version, so people who don't carry calculators around in their pockets can get a sense of what the temperature is in the 'other' scale. It'll be a few degrees either way at the extremes, but for the average Joe, it work just fine. Take it or leave it....

Chris......

I guess its the Engineer in me. I can't understand why someone would want to know something and then be satisfied with the wrong answer.

"Close" only applies to horseshoes and hand grenades.

EVERYONE has a calculator in their pocket. Every tweeter comes with one standard. Regardless, googling "xF=C" gives the correct answer in seconds, with no need to have to mentally make a calculation.

***************

But who cares? Went out in my Son's "yacht" yesterday, first boatride of the year. Had to use a muddy unimproved ramp, which ain't easy for a 25 footer.

Got my launch permit today, the officials say the docks are going in tomorrow. Be out in the river Tuesday. The water is now at 42 F, or is it C, I forget. Still too cold for skinnydipping. Life is good.

 

[sphelps]

You need a launch permit ?

 

[JimS123]

You need a launch permit ?

My township has 3 parks with boat launches. Six lanes in each. Parking for 60 cars. Floating docks, daily maintenance by park's personnel and 24 hour surveillance by the police. Maintenance even includes washing down the docks if an errant goose walks by. In the olden days on a Sunday the lot was full. Now sparse attendance after they put on a fee.

I can drive 1 mile away to a county ramp for free. Goose poop on the docks and a lot full of yahoos that try to launch broken boats without a clue.

Yes, I need a permit. $30 a year. Best money I ever spent.

That's were you want the beer at :very_drunk:

It's also the only temperature were water can be; a solid & liquid

 

[JimS123]

I always thought the optimum beer temperature was 45 F., with a certain +- range. 32 is too close to having ice on the head.

 

[The Force power]

You're right, but some do

 

[nola mike]

That's were you want the beer at :very_drunk:

Only if you're drinking swill. That's why they have that think on the coors light cans. It tastes like water when cold, but **** when warm.

Any beer in my opinion not cold taste like *iss:grumpy:

Then why didn't you post the correct formula?
