Calculators

Calculates the number of light bulbs needed to adequately illuminate a room based on its dimensions, desired light level, and bulb specifications.

Converts a decimal inch measurement into its equivalent fractional representation (inches and fractions of an inch).

Estimates the volume and weight of soil needed for your garden or landscaping project based on dimensions and soil density.

Calculates the estimated force needed to punch a hole in a material. This is based on the material's shear strength, the thickness of the material, and the perimeter of the hole.

Calculates the grade (slope) of an elevation change, expressed as a percentage. This is often used in construction, landscaping, and surveying to determine the steepness of a slope.

Calculates the spindle speed (RPM) and feed rate for machining operations based on cutting speed, tool diameter, and desired feed per tooth.

Estimates how many items or boxes fit on a standard pallet or how many pallets are needed for a shipment.

Calculates the taper length and angle based on the large diameter, small diameter, and taper length.

Calculates the approximate flow rate of water in Gallons Per Minute (GPM) based on the Pressure (PSI) reading from a pressure gauge. This calculation assumes a standard water pipe size and doesn't account for friction loss or other factors.

Calculates the volume in cubic yards for common shapes like rectangular solids, cylinders, and spheres. Useful for estimating material quantities like concrete or gravel.
