Online-Calculator.com
Online-Calculator.com was created in November 2007 - as part of a hobby project to learn basic programming and web design skills!
Since then, it has become one of the most popular websites on the internet for a range of calculators, conversions, and other maths based applications, apps and tools!
The site has been expanded from the original JavaScript based calculator on the homepage – to a more advanced html5 canvas based calculator – and we’ve continued to use this technology to provide super-simple, user intuitive calculators and conversion tools that simulate real-world designs making it easier for our users to understand how to use the tools we offer.
We are constantly adding new and improved tools and gadgets to the site – even after 17 years! The range of possibilities is endless. We hope you enjoying using the calculators we make as much as we enjoy making them! Thank you so much for using the site – and supporting us for all this time.
