- 1,175 calculators attempt to solve every everyday math problem for you.
- All free to use, it’s amazing how many aspects of life get a calculator.
- Bookmark this collection — it’s hard to imagine you won’t someday need it.
It’s true that high-school calculus teachers torture their students with them, but it’s also true that once some degree of mastery is in hand. Mathematicians love a good — efficient, clever, and useful — formula.
These things aren’t just for classrooms or advanced scientific applications, either. While it’s amazing that formulas predict what will happen if we slingshot a spacecraft around some distant celestial body, they can also be part of our earthly lives calculating all sorts of everyday things.
In any event, for many math heads (carefully typed), slinging formulas together and inventing new calculators is just plain fun. Last week, for example, UK physicist Steven Wooding sent us the link to a calculator he and a friend constructed that predicts contactable alien civilizations. That was fun, but the site to which he directed us is nothing short of dazzling: It’s called Omni Calculator, and it’s a mind boggling repository of 1,175 calculators whose purpose is to help everyone get to the right answers in their personal and professional lives.

Want to know exactly how many balloons it would take to send your house airborne, as in the Pixar’s “Up”? No problem. Hate running unexpectedly out of toothpaste en route to bed? Live your best life. Ditto toilet paper.
Some of the calculators are pretty profound, too, such as the Every Second calculator that shows just how much happens in the world every 60th of a minute — it’s an enthralling set of numbers.
Fun stuff aside, Omni Calculator is an absolutely staggering collection, an incredible resource for normal people and professionals—from doctors, to chemists, to financial advisers, to construction teams, and more.

Omni Calculator is the project of a Polish startup of 24 people dedicated to helping others solve all of the small math problems in their daily lives. The company manifesto:
“In a surprisingly large part, our reality consists of calculable problems. Should I buy or rent? What’s my ideal calorie intake? Can I afford to take this loan? How many lemonades do I need to sell in order to break even? Often times we don’t solve these problems, because we lack knowledge, skills, time or willingness to calculate. And then we make bad, uninformed decisions?”
Omni Calculator is here to change all that — we are working on a technology that will turn every* calculation-based problem trivial to solve for anyone.
The asterisk says, “within reason.”
It all started when founder Mateusz Mucha built a unique web calculator. It could calculate in any direction without a fixed input or output. He invested $80 in translating his Percentage Calculator into 15 languages and stood back as the app was downloaded 4 million times, and counting.
At some point Mucha changed his goal: “Instead of calculating one thing, we’ll calculate all of them — for everybody.” To serve this aim, all of Omni Calculator’s calculators are free to use, developed by the company in collaboration with all sorts of experts.
Go spend some time looking around and bookmarking tools for your own use. You’re pretty much guaranteed to find something that solves a problem with which you’re struggling. At the very least you’ll come across some amazing calculators that will get you thinking about unexpected things.
Omni Calculator also provides a special set of calculators that allow you to crunch COVID-19 numbers for yourself, from a social distancing calculator to one that can predict when your next stimulus check should be due.
