Convert temperatures to and from celsius, fahrenheitΒΆ

Convert temperatures to and from celsius, fahrenheit.
Formula : c/5 = (f-32)/9
where c = temperature in celsius
and f = temperature in fahrenheit
Expected output:
60C is 140 in Fahrenheit
45F is 7 in Celsius
temp = input("Input the temperature you like to convert?\
      (e.g., 45F, 102C etc.) : ")

degree = int(temp[:-1])
i_convention = temp[-1]

if i_convention.upper() == "C":

    result = int(round((9 * degree) / 5 + 32))
    o_convention = "Fahrenheit"

elif i_convention.upper() == "F":

    result = int(round((degree - 32) * 5 / 9))
    o_convention = "Celsius"

else:
    print("Input proper convention.")
    quit()

# test
print("The temperature in", o_convention, "is", result, "degrees.")

Output:

Input the  temperature you like to convert? (e.g., 45F, 102C etc.) : 104f
The temperature in Celsius is 40 degrees.
