What It Does
The HeavyCalc helps you:

Cut Costs & Errors Boost Estimate Accuracy Produce Job-Winning Bids Improve Crew Productivity Maximize Profitability At the estimating table, in the truck or on every crew member's tool belt, the HeavyCalc helps get every job done right the first time! Quickly master the following construction problems, in the office or out in the field:

Area & Volume Calculations Prevent errors & save keystrokes with automatic calculation of area and volumes. Length, Width, Depth, Area & Volume keys allow for fast & accurate material estimates.

Weights Lets you convert between weights (lbs, tons, kg) and find weights of any material (e.g., tons per cubic yard). Figure truckloads and weights and improve your bottom line.

Existing, Proposed & Cut/Fill Keys Simplifies soil-volume cut and fill estimates.

Shrink & Swell Solve Bank, Compacted and Loose soil volumes for any job.

Percent Grade and Slope Instant right-angle solutions for finding diagonals, square-ups, and staking-out drops, grades, ramps, drainages, trenches, and more! No more formulas or memorization of Pythagorean theorem!

Average Function Speeds grid-cell cut/fill estimates.

Dimensional Math & Conversions Works in all dimensional formats: quickly add, subtract, multiply, divide and convert in feet-inches-fractions, decimal feet, decimal inches, inches and fractions, yards, meters, millimeters, board feet, as well as square and cubic formats.

Handles all fractions-1/2's, 1/4's, 1/8's, 1/16's, 1/32's, 1/64's Work in fractions for all sorts of dimension problems. You can even set fraction denominators to display your desired accuracy (in above fraction formats).

Additional Features: "Smart" Fraction Setting Saves keystrokes by entering preset fraction denominators for you, from 1/2 to 1/64.

Paperless Tape Lets you review the last 20 entries, for double-checking answers.

Standard Calculator Works as a regular math calculator, for your everyday math needs.
