| Square-Ups & Right Angles | Helps calculate diagonals and square-ups for layout work, staking, forms, and field measurements. |
| Grade & Slope | Percent grade and slope functions help solve right-angle layout, ramps, trenches, stakeout drops, and elevation-related calculations. |
| Cut/Fill Estimating | Built-in cut/fill, existing, and proposed functions simplify soil-volume estimates for excavation and grading work. |
| Swell & Shrink | Calculates percent swell and shrink to help estimate loose fill, compacted material, and adjusted earthwork volumes. |
| Weight Per Volume | Finds material weight and converts between pounds, tons, kilograms, and metric tons. |
| Truck Load Estimating | Calculates trucked loose-fill volume and uses swell or shrink factors to help determine total weight and load requirements. |
