Convert length, area, volume, and mass between US customary and metric units.

Solve part/whole percentages, percent change, and ratio-style comparisons.

Rectangular pits, trenches, and cylinders — cubic yards and cubic feet.

Estimate tonnage from volume using typical aggregate and soil densities.

Concrete volume for round piles from diameter and length; optional quantity.

Translate volumes using swell and compaction yield factors common in earthwork.

Convert rise/run to percent grade and ratio for layout and checks in the field.

Estimate internal volume of a pipe run from ID and length for utility work.

Reinforced concrete pipe: bore volume plus concrete shell from ID, wall thickness, and run length.

Bore volume and wall annulus from ID, optional OD or wall thickness, and length — with a dual-ring diagram.

Round pipe (water/sanitary PVC, RCP, HDPE) and box culvert bedding — pick a size, auto-fill OD and side clearance, get CY/LF and tons.

From horizontal run and vertical rise: slope length, percent grade, and slope angle.

Rectangular slab: length, width, and thickness to cubic feet and cubic yards for flatwork estimates.

Convert feet of water column to PSI (and kPa) for head checks and rough pump conversations.

Convert between cfs, gpm, MGD, L/s, and m³/s for dewatering and line sizing discussions.

Add or subtract distance from a US-style station (e.g. 10+00) for quick chainage math.

Time to move a volume at a steady flow rate — tanks, pits, and pump curves (steady-state only).
