As tittle says, I just found it too .
If you guys have some more sites just post them.
It might be interesting.
I happen to use this one: https://www.unitconverters.net/
Oh, thx for sharing @nwg
Bookmarked in my FF s , looks interesting !
In my case I always need to know how many degrees centigrade is Fahrenheit.
So, for example, if the dashboard on my bike shows 190 •F and I want to know how many •C it is, I do the following math:
190 - 32 = 158
and then 158 I multiply by 5 and divide by 9.
The result is = 87.7 •C
Oh, good tip @judd
If you don’t have to know the exact number, use a simpler formula,
(F - 30) / 2 = C
It’s just not that exact, but it works!
Thank you @chroot
Pretty much it but when it goes colder it kind of evens out oddly enough temperature-wise F to C and C to F degrees.
