The two temperature scales that are most commonly used are Fahrenheit and Celsius. Knowing how to convert Celsius to Fahrenheit is useful because it allows programmers to manage temperature calculations when creating weather-related apps.
Let’s first discuss the formula for converting Celsius to Fahrenheit.
Using the formula below, we can change the temperature from Celsius to Fahrenheit:
Here, is the Fahrenheit temperature, and is the Celsius temperature.
We need to apply the above formula to a provided temperature value to convert it from Celsius to Fahrenheit.
Let’s suppose we have a temperature of degrees Celsius. Let’s put the value of in the formula above,
Given that ,
Now, let’s see an example of converting a temperature in Celsius to Fahrenheit in Java:
public class CelsiusToFahrenheit {public static void main(String[] args) {double c = 30;// Using the formuladouble f = (c * 9/5) + 32;System.out.println("After converting celsius to fahrenheit the value is " + f);}}
Line 1: Define a public class named CelsiusToFahrenheit.
Line 2: Define the main method, which is the starting point of the Java program.
Line 3: Define a double variable c and declare and initialize it with the value
Line 6: Calculate the temperature in Fahrenheit using the formula for converting Celsius to Fahrenheit. It multiplies the Celsius temperature (c) by f.
Line 7: Print the result.
