About this app
Totient is the measurement calculator for people who work in feet, inches, and fractions — woodworkers, DIYers, makers, and anyone who measures twice and cuts once. Type a measurement the way you read it off a tape — 5 ft 4 5/8 in — and Totient does the math a basic calculator can't. Add, subtract, multiply, and divide in feet-inch-fractions, then see the answer rounded to the precision you choose, from 1/2 down to 1/64. Switch to Area or Volume and your numbers carry across — measure a length, step up to area, then to volume, without re-entering anything. Every result shows its conversions at a glance — feet, inches, yards, centimeters, and meters — and in Area and Volume, square yards and cubic yards too, so imperial and metric sit side by side. Keep a running history of your calculations, and copy any result to the clipboard — the value on its own, or the value with its units — plus the full saved calculation, so it drops straight into a cut list, an order, or your notes. WHY TOTIENT - Built for feet-inch-fraction math, not adapted from a basic calculator - Length, area, and volume in one place, with results that carry between them - Precision you control, from 1/2 to 1/64 - Imperial and metric together — feet, inches, yards, square and cubic yards, centimeters, meters - Calculation history — every result saved to scroll back through - Copy to the clipboard: value only, value with units, or a saved calculation - Free — no ads, no subscription, no account - Works fully offline — on the bench, in the shop, or on site Made for woodworking, carpentry, home improvement, remodeling, and any project where a fraction of an inch matters.
