That is pure coincidence.
40 degrees Fahrenheit, as 20 degrees Celsius equals 68 degrees Fahrenheit
minus 40 degree celsius is equal to minus 40 degree fahrenheit, -39 degree Celsius = -38.2 degree Fahrenheit -40 degree Celsius = -40 degree Fahrenheit -41 degree Celsius = -41.8 degree Fahrenheit the degree celsius and degree fahrenheit coincides here correctly..!
40 degree Celsius = 104 degree Fahrenheit.
40 degree Celsius = 104 degree Fahrenheit
40 degrees Celsius = 104 degrees Fahrenheit.
(-40) degrees Fahrenheit = -40degrees Celsius
At -40 Celsius and Fahrenheit are the same temperature.
15 degree Celsius = 59 degree Fahrenheit.
A temperature of 40 degrees Celsius is equivalent to 104 degrees Fahrenheit.
It is also -40-40 degrees Celsius equals - 40 degrees Fahrenheit. Easy to remember.
104ºF = 40.0ºC
The temperature where Celsius and Fahrenheit are the same is -40 degrees.
