EasyAdd

EasyAdd is a tape measure calculator. Type measurements the way your tape reads them, like 1' 2 1/2", and get answers back the same way: 1' 6 3/8".

BUILT FOR THE JOB SITE
• Feet, inches and fraction keys: tap 1/8 through 7/8, or switch to sixteenths
• Exact math with no rounding drift. Answers round to the nearest 1/16" (or 1/2" to 1/64", your choice) and show ≈ when rounded
• Add, subtract, multiply and divide, with a live answer as you type
• Length × length gives square feet; three lengths give cubic feet or yards
• Mix in metric: type mm, cm or m and get feet and inches back
• Tap a result to switch between feet & inches, inches, decimal feet, mm, cm and m
• Backspace one key at a time, or bring back the last calculation to fix a typo
• Memory keys and a saved history of your last 50 calculations
