Just follow instructions in project. This converts Celsius, Fahrenheit and Kelvin. It will give you the choice to swap units. When you get your conversion click the green flag if you need another one. If your answer seems wrong please check you're using the right scales and you're not using a negative value for Kelvin, and if it turns out it's wrong let me know ASAP.
Note: the converter sometimes says answers to LOADS of decimal places but it should be completely accurate. I can't use the round block because it'll round it to the closest integer which isn't accurate enough.
