CalculatorHub.app is a free online calculator website that allows you to calculate, convert, or solve problems in math, physics, science, finance, health, and more. We also have detailed explanations, formulas, examples, and FAQs for each calculation page to help you understand how it works.

Additionally, you can install any calculator as a web app for easy and quick access on any devices running recent Android, iOS, Windows, and macOS operating systems.

Our Story

Tithdara, the founder of the CalculatorHub.app, has always been fascinated by web and app development to create helpful resources for the world. As a casual app developer, he has developed and published over 20 local educational apps on Google Play Store and Microsoft Store with over one million total downloads.

Maintaining multiple apps on multiple app stores has never been easy. That’s why he created this website to host calculator web apps and adopted the progressive web app (PWA) technology, which allows those apps to run or install on any modern browser, smartphone, tablet, or PC.

Our Mission

Like our first web app, the aspect ratio calculator, we developed it to help the PC gaming and graphics designing community define a suitable resolution of an image or video based on the original ratio. Our goal is to make people’s lives easier with our calculators that cover various topics such as math, science, physics, finance, health, and more.

We commit to providing highly accurate results and a user-friendly interface to tackle challenging problems with simple solutions.

The Team

Our team is working hand in hand to develop calculators that are easy to use and accurate for everyone. We also ensure that the information provided is correct and reviewed by specialists and academics from corresponding fields.
