With this calculator you will calculate the average absolute deviation, or mean absolute deviation (MAD), of a data set is the average of the absolute deviations from a central point.

The calculator is used to calculate the ventilation capacity in an attic or loft for the minimum, normal and extreme thermal conditions of the environment depending on the area and height of the room and the roof pitch. The fan removes warm air from the room and should be mounted at the highest possible point for the best efficiency.

With this calculator you will perform a complete analysis of the quadratic function with explanations. The calculator will determine the zero points of the function, the coordinates of its vertex, calculate the delta and present the product and the canonical form of our function. R

Parallelogram calculator will help you calculate the long diagonal of the parallelogram, the short diagonal of the parallelogram, the side length, heights, area of the parallelogram.

With this calculator, you will calculate the exact tire pressure required for your bicycle tires on the front and rear wheels depending on the load, wheel size, bicycle weight, etc.

The calculator is designed to calculate the amount of bricks or blocks needed. How many bricks do we need to build a wall of the given size, including wall openings and joints, how many bricks should we order, taking into account waste and what will be their weight.

Using the calculator you can calculate the partial pressure according to Daltons law.

Height calculator will help you calculate what height your child will have in the future, ie when it stops growing. Predicted Adult Height

Using the calculator, you will calculate the basic metabolic rate (BMR-basal metabolic rate) and the amount of calories needed to supplement, i.e. burned by the body on an empty stomach (in the morning, without a meal), in physical and mental peace.

Thanks to the calculator, you can easily calculate the area of a square, the side of the square, the diagonal of the square, the radius of the circle inscribed and described on the square.

Rectangle calculator will help you calculate the diagonal of the rectangle, the side length, height, area of the rectangle.

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.

Using this translator / converter you can quickly and easily check how to spell each word using the international (and not only) phonetic alphabet.

With this calculator you will calculate the voltage drops for single-phase and three-phase AC circuits calculated from active power. You will also calculate cable length, conductor diameter, conductor cross-sectional area, phase or line voltage or active power.

Using the calculator, we will calculate the water lost from the body and the percentage of weight loss after the exercises.

With this calculator you will calculate the harmonic mean.

Triangle calculator will help you calculate the area, perimeter, sides, height, angles of any triangle, right triangle and equilateral.

You can calculate with explanations any system of linear equations, both homogeneous and heterogeneous with any number of unknowns by Gauss-Jordan elimination method. As a result, apart from the solution, you will also receive a complete analysis and a step-by-step calculation.

Using the calculator, you will calculate the resting metabolic rate (RMR) and the amount of calories needed to supplement, i.e. burned by the body while resting.

The reactive power calculator in AC circuits will help you easily calculate reactive power, voltage and current.
