You want a easy way to convert Fahrenheit to Centigrade? Subtract 30 and divide by 2

  This is a shitpost? Seems like a LPT as a useful, quick approximation, since the real formula is “subtract 32, divide by 9/5”. 30≈32, and 2≈9/5, as long as you’re figuring out what to wear for the day, not working in a chemistry lab. (Don’t burn your meth, fer gawdsakes!)

  For 32°F, the approximation is 1°C, and even where the scales align at -40°, it works out to -35°C.

    Mickey does grandpa-posting. You get used to it.

    Cool info, anyway

  Honestly, no, I don’t want an easy way to convert.

  I generally dislike temperatures.

  Why are we using letterhead to do our thermobaric calculations?

  Is this true? If so, I like it a lot.

  Is it a lie, hence a shit post? If so, I must cleanse my mind again.

  I’m going to have to do the math, aren’t i? And verify whether or not it’s true…

    No, it’s not true. Another has the actual formula, but the proof that it’s incorrect is that 32°F = 0°C, while (32-30)/2 = 1.

      That’s what I call good enough.

    The actual formula is subtract 32 and multiply by 5/9.
    But this is a lot easier, and is very close for all temps you’ll encounter as weather.
