The easy-to-use ConcreteCalc Pro helps reduce material waste, improve design accuracy, and cut estimating time.

Increase efficiency in the field or in the office with fast, accurate solutions for Square-ups, Loads, Area, Volume, Rebar, Drop, Stairs, and much more.

It helps you:

• Work in Yards, Feet-Inch-Fractions
• Calculate Area, Volume, and Weight per Volume
• Automatic Square-ups and Drops
• Rebar solutions for total Linear Feet and Weight per size
• Complete Stair Layouts; set Riser Height and Tread Width
• Equal Sided Polygons
• Circular Solutions: Circumference, Arc, Cone, Column, and More!
• For Concrete, Masonry, and Paving Professionals

Dimensional Math and Conversions:

Work in and convert between building dimensions: Yards, Feet-Inch-Fractions, and Metric – including Square and Cubic formats. Automatic Weight per Volume; select Pounds, Tons, Kilograms, or Metric Tons. D.M.S. to Decimal Degree Conversions.
