This calculator calculates the heat index or apparent temperature.

The calculator is a useful tool for calculating the total area of a set of rectangles.

Generate seating chart combinations based on students' seating preferences using a genetic algorithm.

The RGB-HSV Color Converter allows the user to convert RGB color values to HSV color values and vice versa.

This calculator generates palette of colors from starting color to ending color, using maximum diversity, "rainbow" style.

This calculator is used to set the air flow rate through a grain bin equipped with an aeration fan. It assumes that the air flow can be controlled with baffles, spill gates or variable fan speed. It requires an air flow meter or anemometer. This calculator determines the air speed needed at the top collar of bin in order to achieve the desired air flow rate (CFM/bu Cubic Feet per Minute per bushel).

This online calculator finds the height above the bottom of a horizontal cylinder (such as a cylindrical gas tank) to which the it must be filled for it to be full at specified percentage (for example, one quarter full amounts)

This online calculator uses the Box–Muller transform to generate a sequence of normally distributed random numbers from a source of uniformly distributed random numbers.

The calculator generates an ordered sequence of numbers from a given range. For example, the order in which the numbers are drawn in a lotto - numbers from 1 to 90 will be listed in random order, or a lottery like 5 out of 36.

The cache calculator gives the volume and weight of the cache in a currency.

This online calculator converts given CaCl2 ppm concentration into chlorides water phase salinity ppm concentration

This online calculator calculates the normal force's strength from the object's mass, the gravitational field strength, and the inclined surface's angle measured from the horizontal.

Use this to determine the baffle plate gap in a tank based on your throat size. Measure bell end depth using something the same width as your baffle plate or enter a zero if there is no belled end. The drawing is looking from the top down.

Calculate unknown values (force, charge, or distance) using Coulomb's law scalar formula with this online calculator. Solve physics problems with ease.

This article lists several calculators to compute the area of a quadrilateral

This online calculator uses several regression models for approximation of an unknown function given by a set of data points.

This online calculator takes a system of linear equations and applies Cramer's rule to solve it, showing all intermediate steps in the process.

If you want to made a DIY sphere, you need to unfold the sphere to 2D shapes, or, more strictly speaking, approximate the sphere using petals, or "orange peels" (also called the lunes) on the plane. The calculator calculates basic parameters of such 2D peel and displays coordinates of points for drawing one peel on a plane.

This online calculator solves a system of linear algebraic equations using the Gaussian elimination method. It produces the result whether you have a unique solution, an infinite number of solutions, or no solution. It also outputs the result in floating point and fraction format.

This calculator provides access to 752 world development indicators for Cuba imported from World Bank data at 2016. In memory of Fidel Castro.
