# Temperature Converter

## Program Listing

• This program will convert temperatures from Fahrenheit, Celsius, or Kelvin to the equivalent temperature in all three systems

### TempConverter.cpp

 ```/************************************************************************ * * * Program: TempConverter.cpp * * * * Purpose: This program will read a temperature in either * * Fahrenheit, Celsius, or Kelvin and convert it to the * * equivalent temperature on all three scales. * * * ************************************************************************/ #include #include using namespace std; int main() { cout << "Enter a temperature in Fahrenheit, Celcius, or Kelvin," << endl; cout << "followed by F, C, K to indicate the scale (e.g., 39 F): " << endl << endl; int temp; char scale; cin >> temp >> scale; int tempF; int tempC; int tempK; // Select the case based on the scale used switch (scale) { // Convert Fahrenheit to Celsius and Kelvin case 'F': case 'f': tempF = temp; tempC = round(5.0/9.0*(tempF - 32)); tempK = tempC + 273; break; // Convert Celsius to Fahrenheit and Kelvin case 'C': case 'c': tempC = temp; tempF = round(9.0/5.0*tempC + 32); tempK = tempC + 273; break; // Convert Kelvin to Fahrenheit and Celsius case 'K': case 'k': tempK = temp; tempC = tempK - 273; tempF = round(9.0/5.0*tempC + 32); break; // Invalid input default: cout << "Invalid temperature scale.

### Sample Run #1

 ```Enter a temperature in Fahrenheit, Celcius, or Kelvin, followed by F, C, K to indicate the scale (e.g., 39 F): 32 F The temperatures are 32 F = 0 C = 273 K ```

### Sample Run #2

 ```Enter a temperature in Fahrenheit, Celcius, or Kelvin, followed by F, C, K to indicate the scale (e.g., 39 F): 100 C The temperatures are 212 F = 100 C = 373 K ```

### Sample Run #3

 ```Enter a temperature in Fahrenheit, Celcius, or Kelvin, followed by F, C, K to indicate the scale (e.g., 39 F): 0 K The temperatures are -459 F = -273 C = 0 K ```
