Everyday Calculators
A fast, private, browser-only suite of everyday formula calculators. Plug in the values you know, and the tool solves for the missing one - travel time, download time, tips, percentages, and more.
What it is
Thirty calculators across seven categories (Motion & Travel, Downloads & Data, Time & Date, Money, Health & Fitness, and Home & Energy) - each one a simple, single-purpose formula. Everything runs on your device.
How to use
Pick a category, pick a calculator, and type in what you know. Results update as you type. On the speed and download calculators, leave one field blank and the tool solves for it.
Privacy
Nothing you enter leaves your browser. There is no account, no server, no tracking, and no saved history. The only thing stored is your light/dark theme preference, on this device.
