This Program helps with conversion in Temperature Instructions: Select Units of Temperature you are in For Example- If I have my temperature in 30 degrees Celsius, then choose Celsius at beginning of the Menu. Then type in the number you have without the degree symbol- for instance type in 30 after choosing degrees. The answers in both of the other units will show up, just choose the one you need and exit the program if done I am not liable for any wrong answers or malfunctions of the calculator. Have Fun!! -JF
