Table of Temperatures... Help

How does this look? 

user = int(input("Enter a Number: "))

def fahrenheit(celcius):
        return (celcius * 9 / 5) + 32
    
def main():
    print("Celcius \t Farenheit")
    
    for t in range (user):
        print(t, "\t\t ", fahrenheit(t))
        
main()

When I enter 25 it will stop at 24 >_<, what did I do wrong this time?
