Find Percentage started out as a project to help people calculate percentage in an easy way. We saw the need of a very user friendly calculation website, so we took it further and made even more calculators, e.g how to calculate BMI (body mass index), fat percentage, currencies and so on. We work hard to continuously make new helpful stuff that people find really useful in their daily life.
We would love to hear from you if you have any comments, ideas or suggestions for further development. Don't hesitate to get in touch!
