With the method shown alongside the outcome, bulk materials, frame math, and the electrical figures required for every job site, gravel, drywall, studs, and volts, were all quickly calculated.
21 of 21 calculators shown
Ground & Paving Materials
6 calculatorsbulk material for base layers, beds, and roadways by weight or volume.
Gravel Calculator
Gravel volume and weight required for a base layer, road, or path.
Volume = Length × Width × Depth Open calculator →Topsoil Calculator
aka Top Soil CalculatorTo level a yard or fill garden beds, cubic yards of topsoil are required.
Volume = Length × Width × Depth Open calculator →Sand Calculator
Volume and weight of sand needed for a pit, base, or paver joints.
Volume = Length × Width × Depth Open calculator →River Rock Calculator
The amount of river rock required to cover a landscaping bed is measured in bags or tons.
Volume = Coverage Area × Depth Open calculator →Asphalt Calculator
Depending on area and thickness, tons of asphalt are required for a lot or driveway.
Tons = Area × Thickness × Density Open calculator →Bitumen Calculator
The amount of bitumen required to seal or surface a certain area.
Bitumen (kg) = Area × Rate per m² Open calculator →Framing & Structural
6 calculatorsThe math underpinning lumber takeoffs, walls, staircases, and roofs.
Roof Pitch Calculator
Rise and run data are used to calculate roof pitch and angle.
Pitch = Rise ÷ Run Open calculator →Rafter Calculator
Run, rise, and roof pitch rafter length and cut angles.
Rafter Length = Run ÷ cos(Pitch Angle) Open calculator →Stud Calculator
The length and spacing of the wall determine how many wall studs are required.
Studs = (Wall Length ÷ Spacing) + 1 Open calculator →Board Foot Calculator
Board feet of lumber from thickness, width, and length dimensions.
Board Ft = (T × W × L) ÷ 144 Open calculator →Stair Calculator
Step count, tread depth, and riser height for a stairs run.
Riser Height = Total Rise ÷ Number of Steps Open calculator →Linear Feet Calculator
The total linear feet of material required based on the area and width of the board.
Linear Ft = Total Length of Material Open calculator →Interior & Building Materials
4 calculatorsFixture counts, brickwork, and sheet products are used to complete a space.
Drywall Calculator
The overall wall area determines how many drywall sheets are required.
Sheets = Wall Area ÷ Sheet Area Open calculator →Plywood Calculator
The quantity of plywood sheets required to cover a wall, roof deck, or floor.
Sheets = Area ÷ 32 sq ft Open calculator →Brick Calculator
A wall’s area determines how many bricks and mortar are required.
Bricks = Wall Area × Bricks per sq ft Open calculator →Recessed Lighting Calculator
The quantity and spacing of recessed lights required to light a space uniformly.
Fixtures = Room Area ÷ Spacing² Open calculator →Electrical & Specialty
5 calculatorsPool maintenance, wiring, fencing, and engine math for the home.
Voltage Drop Calculator
Voltage lost over a wire run based on gauge, current, and length.
VD = (2 × K × I × L) ÷ CM Open calculator →Watts to Amps Calculator
At a specific voltage, convert power in watts to current in amps.
Amps = Watts ÷ Volts Open calculator →Fence Cost Calculator
Total cost of fence based on labor rate, materials, and linear feet.
Cost = Linear Ft × Cost per Ft Open calculator →Pool Salt Calculator
Pounds of salt needed to raise a pool from its current PPM to target.
Salt (lbs) = Gallons × (Target − Current PPM) × 0.00834 Open calculator →Compression Ratio Calculator
Engine compression ratio based on the volume of the combustion chamber and the swept volume.
CR = (Swept Vol + Clearance Vol) ÷ Clearance Vol Open calculator →No calculators match that search. Try a different word — e.g. “gravel,” “stud,” or “voltage.”
