Which is colder Celsius or Fahrenheit?

Answer 1

At -40 they're the same.

Neither is colder, they are scales of measurements for temperature.

Those are two scales of temperature. Neither can be defined as being colder.

One could say that Fahrenheit is the "colder" scale because -1 degree Fahrenheit is colder than -1 degree Celsius.

The "coldest" scale I know of is Kelvin, which defines 0 degrees Kelvin as -273.15 degrees Celsius (Absolute Zero).

Answer 2

Fahrenheit and Celsius are two different measurements for heat, neither is colder nor warmer.

Answer 3

Celsius is colder than Fahrenheit. In the Celsius scale, water freezes at 0 degrees and boils at 100 degrees, while in the Fahrenheit scale, water freezes at 32 degrees and boils at 212 degrees.
