Torr Calculator

Pressure in Torr:



Pressure conversions are essential in various scientific and engineering applications. This guide will walk you through creating an HTML Torr Calculator, allowing you to convert pressure from Pascals (Pa) to Torr. We’ll provide you with the formula, step-by-step instructions, and code examples to make it simple and accessible.

How to Use

To use the Torr Calculator, follow these steps:

  1. Create a Form: Start by creating an HTML form to gather input from the user.
  2. Input Field: Add an input field for the pressure in Pascals (Pa).
  3. Button: Insert a clickable button within the form for the conversion.
  4. JavaScript Function: Write a JavaScript function to perform the conversion using the formula: Torr = (Pa * 760) / 101325.
  5. Display Result: Display the converted pressure in Torr on the webpage.


The formula to convert pressure from Pascals (Pa) to Torr is:

Torr = (Pa * 760) / 101325.


  • Torr is the pressure in Torr.
  • Pa is the pressure in Pascals.


Let’s say you have a pressure of 101325 Pa. Using the formula:

Torr = (101325 * 760) / 101325 Torr ≈ 760 Torr

So, 101325 Pa is approximately equal to 760 Torr.


1. Why use Torr for pressure measurements?

  • Torr is a common unit of pressure in scientific applications, particularly in vacuum technology and chemistry. It provides a convenient way to express low-pressure values.

2. Can I use this calculator for pressure units other than Pa and Torr?

  • This calculator is specifically designed for converting between Pascals (Pa) and Torr. If you need to convert between other units, you may need a different tool.

3. How do I incorporate this calculator into my website?

  • You can use the provided HTML and JavaScript code examples to implement the Torr Calculator on your website. Just copy and paste the code into your HTML file.

4. What is the significance of the constants 760 and 101325 in the formula?

  • The constant 760 is the number of Torr in 1 atmosphere (standard pressure), and 101325 is the number of Pascals in 1 atmosphere. These constants are used to convert between the two units.


Creating an HTML Torr Calculator is a valuable tool for converting pressure from Pascals to Torr. By following the steps outlined in this guide and using the provided formula and code examples, you can easily implement this calculator on your website or application, making pressure conversions a breeze. Whether you’re a student, scientist, or engineer, this tool simplifies pressure unit conversions for your needs.
