THE CALCULATOR THAT WILL NEVER BE ALLOWED IN EXAMS. omnicalculator.com
The world is full of numbers. Sometimes, you’ll need to get a bunch of these numbers and figure out how they interact, or indeed, what they even mean. Thankfully, Omnicalculator aims to be a one-stopshop for such numerical noodling, providing some severely useful tools in an array of relevant categories. Whether you’re looking to bust out some business, cook up some chemistry, or flirt with some physics, this site will likely have you covered. Beyond its impressively varied categories, there’s a search bar to immediately jump to a relevant tool, or you can check out the most popular calculators to discover something you didn’t even realise you needed to know before now. Each page comes with a range of explanations and relevant facts to help you understand what it is you’re calculating or why it’s important, and of course, an interactive (and embeddable) calculator in which you can input data and churn out a result.
