fahrenheit vs celsius?

Question

is there a temperature at which Fahrenheit thermometer and a celsius thermometer give the same reading? if so, what is it?

Answer 1

40 below zero.

Here's why:
You know that (9/5)C + 32 = F

And you know that at a certain point, F = C

So you can do a little algebra.

9/5 C + 32 = F
9/5 C + 32 = C (C and F are equal at a certain point, and you want kelvin, which is easiest to get from celcius)

Move the 32 from the left side to the right by subtracting
9/5 C + 32 - 32 = C - 32

9/5 C = C - 32

Subtract C from both sides to put all of your variables on the left

9/5 C - C = -32

You know that 1 c = 5/5 c
9/5 C - 5/5 C = -32

Combine like terms
4/5 C = -32

divide both sides by 4/5

C = -40

So when C = -40, then C = F. The two are equivalent at 40 below.

Answer 2

Yes, -40 will be equal in both scales. Here is how:

-40 C = -40 x 1.8 = -72 but we need to add +32 to get Fahrenheit. So, -72 + 32 = -40 F

Answer 3

Fahrenheit's scale grow to be meant to be from as chilly because it ever have been given in his basement to 2 hundred for the boiling component to water, yet he have been given it incorrect. it particularly is not any longer precisely precise. Celsius is meant to be from 0 at freezing under "usual circumstances" to a hundred on the boiling component to water. the same old circumstances are incredibly arbitrary and stressful to reproduce accurately. Scientists use Kelvin, that's set between absolute 0 and the triple component to water. Celsius and Fahrenheit are actually the two defined in terms of Kelvin. there is an attempt to redefine the Kelvin based on Boltzmann's consistent, to make it extra precise and ordinary to reproduce.

Answer 4

-40 F. = -40 C.

Answer 5

Yes indeed. -40 degrees C or F.

Answer 6

when c=-40 and f=-40
we can represent this no graph too!
