Trade and industry calculators
Calculate a material tally or check the measurements for a job. These tools cover construction, maintenance, manufacturing, logistics, printing, baking and sewing. Enter your product yields, dimensions and limits. Results show the units, measurement references and assumptions needed to compare them with your job specifications.
Concrete volume and bag estimator
Add slabs, footings and round piers to estimate concrete volume, whole bags and material cost from your product yield.
Brick and block estimator
Subtract wall openings, include mortar joints and estimate whole units and packs with a visible waste allowance.
Roof pitch and rafter calculator
Convert roof pitch between rise/run, degrees and percent, and calculate common-rafter centerline and overhang geometry.
Stair rise and run planner
Compare equal-riser layouts, choose the top landing and check tread dimensions against your entered constraints.
Tile layout and cut planner
Preview a rectangular tile grid, compare centered layouts, inspect edge cuts and estimate whole boxes.
Paint coverage and can estimator
Measure rooms and openings, then estimate finish paint and primer cans using your coverage, coats and allowance.
Lumber board foot estimator
Add a lumber list, keep actual and quoted dimensions separate, and calculate board feet, volume and cost.
Pipe rolling offset calculator
Calculate true offset, travel, advance and roll angle, then enter actual fitting takeouts for a straight cut length.
Conduit offset calculator
Calculate ideal two-bend spacing and shrink, and compare them with your verified bender multipliers and mark references.
DC cable voltage drop calculator
Estimate two-wire DC drop and power loss from a cable specification, measured loop resistance or supplied resistivity.
HVAC airflow and duct calculator
Calculate actual duct airflow, mean velocity or required area with clear metric and imperial units.
Machining speeds and feeds calculator
Convert supplied cutting speed and chip load into RPM and feed, then compare actual settings with entered machine limits.
Sheet metal bend allowance
Calculate one bend's allowance, setback, deduction and flat blank length using explicit outside-flange datums.
Pulley and belt drive calculator
Calculate ideal driven RPM, pitch-line speed and geometric open-belt length from pitch diameters and center distance.
Pallet layer and stack planner
Compare carton orientations on a pallet and calculate full layers under entered total height and gross mass limits.
Print sheet yield and cut layout
Plan rectangular pieces per sheet with print margins, bleed, gaps and grain restrictions, then export the cut map.
Baker's percentage and dough scaler
Scale a flour-basis formula by dough mass, flour mass or piece count, with preferment accounting and printable weigh-outs.
Fabric yardage and repeat planner
Estimate roll length for rectangular fabric pieces with seam allowance, straight repeats, grain and nap restrictions.
Dilution and batch ratio calculator
Calculate concentrate and diluent amounts with explicit product-to-water or product-to-total ratios and matching volume concentration bases.
Mulch, soil and gravel estimator
Total multiple beds or paths, separate compaction from purchasing allowance, and calculate whole bags or bulk volume.
