Tap digits, the foot/inch keys, and fraction presets to build a dimension (e.g. 14′ 7 3/8″), then tap an operator and build the next one. Press = for the result, copy it, copy decimal feet, or push the measurement straight into your estimate as a reference line.

Tap keys to build a dimension
—
Add, subtract, multiply, and divide dimensions like 14 ft 7-3/8 in with big touch-friendly keys.
Tap digits, the foot/inch keys, and fraction presets to build a dimension (e.g. 14′ 7 3/8″), then tap an operator and build the next one. Press = for the result, copy it, copy decimal feet, or push the measurement straight into your estimate as a reference line.
All arithmetic runs in integer 16ths of an inch no floating-point drift, fractions stay exact.
Every result shows the reduced fraction plus decimal inches, decimal feet, and metric equivalents.
Operations evaluate left to right (× and ÷ have no precedence) the same way chain calculators work.
14' 7-3/8" + 9' 11-1/2" = 24' 6-7/8"
Enter a dimension like 14' 7-3/8", tap +, enter the next dimension, and press =. The keypad does all math in integer 16ths of an inch, so the reduced-fraction result is exact, not rounded.
Every result shows the reduced fraction plus decimal inches, decimal feet, and metric equivalents, so one entry gives you feet-inches, decimal, and metric at once.
Phone calculators use floating-point decimals, so errors like 0.1 + 0.2 accumulate across chained cuts. This keypad works in integer 16ths of an inch, the same way you would work it on paper, so fractions stay exact.
Yes. After pressing =, tap an operator to continue from the last result, or keep building expressions left to right. Recent calculations are saved on the device for the day.
Tap 9, the ft key, 1, 1, the 1/2 preset, and the in key. The display reads your entry back as a live dimension preview so you can verify it before pressing =.
