Calculators

Calculates the area of a rectangular space given its width and length, and converts the result between various area units.

This calculator determines the expected delivery date for llamas based on the date of conception. Llamas typically have a gestation period of about 350 days.

Calculates the required production rate to meet customer demand (available time / customer demand). Takt time is the rate at which a product must be completed to meet customer demand.

Evaluates the performance of a classification model using metrics derived from a confusion matrix, including accuracy, precision, recall, and specificity.

Calculates the number of permutations (arrangements) of a set of items, where the order of selection matters.

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 maximum theoretical efficiency of a heat engine operating between two temperatures.

Calculates the electric field strength created by a point charge.

Calculates the minimum speed needed for an object to escape the gravitational influence of a celestial body.

Calculates the angle of refraction of light as it passes from one medium to another, using Snell's Law. This law describes how light bends when it transitions between two different substances with varying indices of refraction.
