# C++ Exercises: Convert temperature in Kelvin to Celsius

## C++ Basic: Exercise-25 with Solution

Write a program in C++ to convert temperature in Kelvin to Celsius.

Pictorial Presentation:

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

int main()
{
float kel, cel;
cout << "\n\n Convert temperature in Kelvin to Celsius  :\n";
cout << "------------------------------------------------\n";
cout << " Input the temperature in Kelvin : ";
cin >> kel;
cel = kel - 273.15;
cout << " The temperature in Kelvin    : " << kel << endl;
cout << " The temperature in Celsius : " << cel << endl;
cout << endl;
return 0;
}

Sample Output:

Convert temperature in Kelvin to Celsius  :
------------------------------------------------
Input the temperature in Kelvin : 300
The temperature in Kelvin    : 300
The temperature in Celsius : 26.85

## C++ Programming: Tips of the Day

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
