Calculadoras de Home & Construction
Concrete, paint, tile and materials.
Concrete
Calculate how much concrete you need for a slab or footing in cubic yards, and how many 60 lb or 80 lb bags it takes. Enter length and width in feet and thickness in inches.
CalculateHome & ConstructionSquare Footage
Calculate the square footage of a room or area from its length and width in feet, for multiple identical areas. Shows the total in square feet and square meters.
CalculateHome & ConstructionPaint
Work out how many gallons of paint you need from the wall area, the number of coats and the coverage. Subtract doors and windows for an accurate estimate.
CalculateHome & ConstructionTile
Calculate how many tiles and boxes you need for a floor or wall from the area and the tile size, with a waste allowance for cuts and breakage.
CalculateHome & ConstructionMulch
Calculate how much mulch you need in cubic yards and 2 cu ft bags from the bed area and the depth you want. Bulk vs bagged made easy.
CalculateHome & ConstructionGravel
Calculate how much gravel you need in cubic yards and tons from the area and depth. Gravel is usually sold by weight, so the tonnage is what to order.
CalculateHome & ConstructionRoof Pitch
Convert a roof’s rise and run into pitch (X:12), angle in degrees and percent slope, plus the slope factor to turn the footprint into the actual roof area.
CalculateHome & ConstructionBrick
Calculate how many bricks you need for a wall from its square footage and the brick size, including the mortar joint and a waste allowance.
CalculateHome & ConstructionRoofing
Calculate roofing squares and how many shingle bundles you need from the roof area, with a waste allowance. Uses the actual roof area, not the ground footprint.
CalculateHome & ConstructionDrywall
Calculate how many drywall (sheetrock) sheets you need for a wall or ceiling, for one or two sides, plus an estimate of screws — with a waste allowance.
CalculateHome & ConstructionFlooring
Calculate how many boxes of flooring you need — laminate, vinyl plank, hardwood or tile — from the room area and the coverage per box, with a waste allowance.
CalculateHome & ConstructionPool Volume
Calculate the volume of a rectangular or round pool in US gallons from its dimensions, and estimate how long it takes to fill from a garden hose.
CalculateHome & ConstructionWater Tank Size
Calculate a water tank capacity in US gallons from its dimensions, and compare it to the reserve you need from the number of people, daily use and days of storage.
CalculateHome & ConstructionGrout
Estimate how many pounds of grout and thinset mortar you need to set and finish a tile job, from the tile area and the coverage per square foot, with a waste allowance.
CalculateHome & ConstructionSolar Panel
Estimate the solar system size in kW and how many panels you need from your monthly electricity use and the peak sun hours in your area, with the roof area required.
CalculateHome & ConstructionElectricity Cost
Work out what an appliance costs to run from its wattage, hours of use and your electricity rate — per day, month and year in kWh and dollars.
