The calculator has been rebuilt, and it's built for the trades! Workman's Construction Calculator is the best, and simplest construction calculator available on the App Market. With the most intuitive way to calculate measurements. Work with Feet, inches, yards, meters, and regular numbers. Simultaneously! Never before has a calculator worked like this! Do you want to put in 3/16 of an inch? Press the numerator button, click 3, and click 16 afterward, done. Yes, 16. One of the unique parts of Workman's Calculator is that the buttons change. When selecting a numerator only odd values are shown (1, 3, 5, 7, 9). After clicking one of the values the appropriate denominator values appear. If the numerator is 9 or higher, automatically 16 is selected. The denominators will always be more than the numerator. Need to multiply by a decimal? Go ahead. Choose how you wish to view your calculations. • Feet • Inches • Decimals Workman's Calculator is about being quick and getting you your calculations that you need, so there's more time getting done what needs to be done and less time on the phone.
