In this article we will show you how to convert from Celsius to Fahrenheit and from Fahrenheit to Celsius
We use the following formulas
To convert from Celsius to Fahrenheit:
F = (C * 9) / 5 + 32;
To convert from Fahrenheit to Celsius:
C = (F – 32) * 5 / 9;
Where F = Fahrenheit and C = Celsius.
Example
Convert from celsius to fahrenheit
using System;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
double fahrTemp, celsTemp;
// get the user input
Console.Write("Enter the temperature in Celsius:");
celsTemp = Convert.ToDouble(Console.ReadLine());
//convert using the formula
fahrTemp = (celsTemp * 1.8) + 32;
//display results
Console.WriteLine("Celsius is {0} -> Fahrenheit is {1}", celsTemp, fahrTemp);
Console.ReadLine();
}
}
}
Here is a test run
Enter the temperature in Celsius:20 Celsius is 20 -> Fahrenheit is 68
Convert from celsius to fahrenheit
using System;

{
static void Main(string[] args)
{
double fahrTemp, celsTemp;
// get the user input
Console.Write("Enter the temperature in fahrenheit:");
fahrTemp = Convert.ToDouble(Console.ReadLine());
//convert using the formula
celsTemp = (fahrTemp - 32) * 5 / 9;
//display results
Console.WriteLine("Celsius is {0} -> Fahrenheit is {1}", celsTemp, fahrTemp);
Console.ReadLine();
}
}
}
