Answer to Question #104960 in Physics for Nyx

Question

Two thermometers are calibrated, one in degrees Celsius and the other in degrees Fahrenheit.
At what temperature are their readings numerically the same?
Answer in units of K.

Answer 1

To change degrees Celsius in degrees Fahrenheit, the formula is:

$$F = 1.8C +32$$

So,

$$C = 1.8C +32$$

$$C = -40$$

$$T=-40+273.15=233.15\ K$$
