What is 75 degrees fahrenheit in the celsius and kelvin scale?

To convert Fahrenheit to Celsius, remember this equation.
Subtract 32, multiply 5, divide 9.

Or vice versa,
Multiply 9, divide 5, add 32.

So, 75°F to celsius.
75 - 32 x 5 / 9 = 

Ignore PEMDAS for this.

75 - 32 = 43
43 x 5 = 215
215 / 9 ≈ 23.8

To convert to Kelvin, basically do all the steps all over again, but with one more Subtract 32, multiply 5, divide 9, add 273.15.

So, 75 - 32 x 5 / 9 + 213.15

We already know we get 23.8 from the first three steps, so just add 273.15

23.80 + 273.15 ≈ 296.95

Hope this helped :)
