The Calculated Industries HeavyCalc Pro is a construction math calculator with a wide range of features for reliable equipment and manpower planning and estimating. There are built-in functions for quick dimensional math and easy conversions between fractions, decimals, and U.S. and metric units. Other functions add flexibility for finding swell and shrinkage percentage, square-ups, right angles, slopes, and more. It is ideal for engineers, excavators, designers, and professionals working in heavy construction.
Drop, Slope, and Percent Grade
The Calculated Industries HeavyCalc Pro quickly analyzes slopes, drops, and percentage grade. Enter slopes as ratio, percent grade, or angle. Calculations for measuring drops are entered as feet, inches, or percent. Use these functions to determine the drop or slope of a lot, a retainer wall, sloped slabs, plan trenches, and more.
Shrink and Swell Solutions
The HeavyCalc Pro quickly calculates shrinkage and swelling. Easily find the loose or compacted volumes for trucks, construction sites, highway work, trenches, or more. Calculate bank, compacted, and loose fill by entering the shrink and swell percentage. Then, convert smoothly between measurements with one button.
Calculate Right Triangles and Square-up Diagonals, and More
The HeavyCalc Pro calculator solves for right triangles and square-up diagonals. Using this function makes squaring up a concrete slab or an entire lot less time-consuming. Simply press a few keys to determine the precise requirements for a foundation, a driveway, highway, or an area of practically any size.
Calculate the volume of concrete for a job to estimate the material cost. Also measure the area of a lot, and then find the number of truck loads it takes to excavate dirt from it. This calculator measures weight from ounces to tons. So weighing material or equipment is simple. There is also a convenient “Average” function.
Calculate Cut-Fill Requirements
The Cut-Fill function of the HeavyCalc Pro determines the change of elevation on a site. This function helps verify how much land needs to be cut away and filled to make it level. Use this function for a specific area of the lot or for larger grid cells. For grid cells, simply enter and store stake measurements and calculate the area’s cut and fill requirements.
The Calculated Industries HeavyCalc Pro features user preferences, 3 memory slots, recalls the last 20 entries, and auto shut-off to save energy. It includes a hard case, one 3-volt CR2016 battery, and 1 year limited warranty.
