Totient: Fraction Calculator
Flooring, tile & deck math
Free
Add and divide in feet, inches, and fractions, then get area and volume instantly. Free — no ads, no subscription, no account, fully offline.
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.
