Construction Calculators

Angle calculator finds miter cuts, roof pitch, and rafter angles using trig formulas. Outputs degrees, grade, and radians for site layout.

Area/volume calculator solves square footage and cubic yards from dimensions. Rectangles, triangles, circles, and cylinders all supported.

Asphalt calculator converts area and compacted depth into mix tonnage. Results suit driveways, parking lots, and road resurfacing projects.

Asphalt paving calculator figures tonnage and cost for driveways and roads. Area, depth, and unit price produce a complete material budget.

Brick calculator counts units and mortar using bond-pattern area formulas. Adjust the waste factor for cuts, damaged bricks, and breakage.

CLC block calculator sizes foam-concrete mix ratios and block count for walls. Outputs density, compressive strength, and thermal U-value.

Circular calculator converts radius, diameter, or circumference across all values. Handles round slabs, curved walls, and cylinder volumes.

Concrete volume calculator finds cubic yards for slabs, footings, and columns. Mix-ratio converts volume to bag count and estimated cost.

Decking calculator counts boards, joists, and posts from deck dimensions. Board width, spacing, and waste factor refine the lumber order.

Drywall calculator counts 4×8 sheets from room dimensions and opening sizes. Waste factor covers cutting losses for accurate panel orders.

Fence calculator counts posts, rails, and panels from run length and spacing. Gate openings reduce the total for a precise material budget.

Flooring calculator converts room area to plank or tile count with a waste factor. Covers hardwood, laminate, vinyl plank, and ceramic tile.

Footing calculator sizes spread footings from load and soil bearing capacity values. Includes thickness, punching shear, and rebar output.

Gravel calculator converts area and depth to tons via bulk density values. Covers road base, drainage stone, and decorative landscape fill.

Lumber calculator converts dimensions and quantity to board feet and material cost. Covers studs, joists, rafters, and dimensional framing.

Material cost estimator multiplies unit price by quantity for each material. Waste percentage and markup refine totals for accurate bids.

Mulch calculator estimates cubic yards from bed area and depth via volume formula. Results convert to cubic feet and bag count for purchase.

Paint calculator estimates gallons from wall area divided by spread rate per coat. Door and window deductions cut waste on every order.

Pythagorean theorem calculator solves a²+b²=c² for any missing side or diagonal. The 3-4-5 multiplier squares building corners on site.

Rafter length calculator finds common, hip, and valley spans from pitch and run. Birds-mouth depth and overhang tail are output together.

Rebar calculator counts bars, weight, and lap splice length from slab area and spacing. Covers #3 through #11 imperial and metric bar sizes.

Roofing calculator converts footprint and pitch to roofing squares and shingles. Waste factor covers hip returns, valleys, and ridge caps.

Stair stringer calculator solves rise, run, and stringer length from floor height and tread. Outputs step count and code compliance ratio.

Tile calculator estimates tile count from room area, gap size, and lay pattern. Waste allowance adjusts the total for cuts and breakage.

Unit conversion calculator converts imperial to metric across construction needs. Length, area, volume, and weight all convert in one place.
