Trying to do a temperature convertor

Question

I'm trying to do a temperature convertor but I can't understand e fix this error. Can someone help me out with it?
Tried to put the inputs out of the If Statement, but it doesn't go on.

#The Code
scale = input('Which scale do you want to use? ')

if scale == c2f:
c_f = float(input('Type the value in Celsius: '))
f = (c2f * 1.8) + 32
print('The temperature is', f, 'Fahrenheit.')
elif scale == f2c:
f2c = float(input('Type the value in Fahrenheit: '))
c = (f2c - 32) / 1.8
print('The temperature is', c, 'Celsius')

print(scale)

Answer 1

You need to use quotes as you are comparing the scale input as a string.

# Code
scale = input('Which scale do you want to use? ')

if scale == "c2f": # I added quotes here
c_f = float(input('Type the value in Celsius: '))
f = (c_f * 1.8) + 32
print('The temperature is', f, 'Fahrenheit.')
elif scale == "f2c": # I added quotes here
f_c = float(input('Type the value in Fahrenheit: '))
c = (f_c - 32) / 1.8
print('The temperature is', c, 'Celsius')
