Write a python script to convert a temperature from Celsius to Fahrenheit.
```python
def celsius_to_fahrenheit(temp_in_celsius):
    # Formula to convert Celsius to Fahrenheit
    temp_in_fahrenheit = (temp_in_celsius * 9/5) + 32
    return temp_in_fahrenheit

# Example usage
celsius_temperature = 20
fahrenheit_temperature = celsius_to_fahrenheit(celsius_temperature)
print(f"{celsius_temperature} degrees Celsius is equal to {fahrenheit_temperature} degrees Fahrenheit")
```
