Calculators

Calculates bike speed based on cadence (pedal RPM), gear ratio, and wheel size.

Estimates calories burned while jumping rope based on weight, duration, and intensity.

Calculates the intensity or effect of something according to the inverse square law. This law states that the intensity of a phenomenon is inversely proportional to the square of the distance from the source.

Calculates the rate of heat transfer due to conduction, convection, or radiation.

Calculates the total equivalent resistance of resistors connected end-to-end.

Calculates the mechanical advantage, output force, or output distance of a pulley system based on input parameters.

Calculates the perimeter (boundary length) of various common 2D shapes.

Calculates the sine of an angle (given in degrees or radians).

Calculate your Basal Metabolic Rate (BMR) using the Harris-Benedict equation, which estimates the number of calories your body burns at rest.

Calculates the depreciation of an asset over a specified period using the straight-line method.
