Chalk: Construction Calculator
Publisher Description
Chalk is the construction calculator that speaks your units. Metric first, flawless in feet and inches, and every result shown in both so nothing on site gets lost in translation.
Type measurements the way you say them. The purpose-built keypad takes 5 ft 3 1/2 in one line, with one-tap fraction keys or 2.45 m, or even a mix of both. No more converting in your head, no more decimal-feet guesswork.
