Write a JavaScript program to Convert Fahrenheit to Celsius

In this tutorial, we will discuss the concept of “Write a JavaScript program to Convert Fahrenheit to Celsius”.

In this post, we will learn how to write a program to convert Fahrenheit into Celsius using the scientific equations in JavaScript programming language with an Example program.

Temperature and conversion

Generally, We have known three types of temperature units Fahrenheit, Celsius, and Kelvin. In this article, we are discussing how to convert temperature units Fahrenheit into Celsius. Fahrenheit and Celsius are the measuring units in degrees as ⁰F and ⁰C  respectively.

Scientific equation Celsius = (Fahrenheit-32)*9/5

Code to Fahrenheit to Celsius

Convert Fahrenheit to Celsius

In this program, the user declares and initializes a variable Fahrenheit as 50.00 It will be converted into Celsius, using the scientific equation in the JavaScript programming language.

Program 1

//Program to Convert Fahrenheit to  Celsius
//Ask input from the user
const fahrenheit=50;
const celsius=(fahrenheit-32)*5/9

//Display the result
console.log(`${fahrenheit} degrees Fahrenheit is equal to ${celsius} degrees Celsius.` );

When the above code is executed, it produces the following result

50 degrees Fahrenheit is equal to 10 degrees Celsius.

 

Convert Fahrenheit to Celsius – Entered by user

In this program, the user declares the variable, then the user is asked to enter a value of Fahrenheit. The entered value will be converted into Celsius, using the scientific equation in the JavaScript programming language.

Program 2

//Program to Convert Fahrenheit to  Celsius
//Ask input from the user
const fahrenheit=prompt("Enter a Fahrenheit value : ");
const celsius=(fahrenheit-32)*5/9

//Display the result
console.log(`${fahrenheit} degrees Fahrenheit is equal to ${celsius} degrees Celsius.` );

When the above code is executed, it produces the following result

Enter a Fahrenheit value : 212
212 degrees Fahrenheit is equal to 100 degrees Celsius.
