Calculators


How to calculate anything.

Construction estimating, material take-off, and general planning require research and often, calculation. Over the years, as I have needed to calculate or research one thing or another, I have saved the referenced website in my favorites. It is evident that these websites know the need and importance of calculators and they have provided the heavy lifting. The formulas are ready for your numbers to be plugged in. Press calculate and you have your answer. I have been doing this long enough that I once had a notebook of math, geometry, material conversion and, other formulas that I did by hand and later by handheld calculator. Thank you to those that have developed these easy to use tools.
