Calculator of the arithmetic mean of a series of distributing class intervals.

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 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 the calculator, you can calculate the pressure, volume, temperature and volume of moles of ideal gas.

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.

Is the chosen weight loss plan adjusted to your needs and possibilities and will it bring the expected results?

The key to success in dietary plans is its proper selection. However, too often we choose plans that are not tailored to us, resulting in ineffectiveness and discouragement, and consequently the quick abandonment of the plan.

Use this test to find out also what factors a tailored diet plan should contain and training sessions. And it's best to apply this test to the already selected plan so as not to waste time on a wrong diet and training.

The calculator is used to test your eyesight and recognize the difference in color shades. After clicking on the first lighter field, the calculator will change colors and the countdown will begin. Each test takes 15 seconds. Search for a lighter field and click on it. Each subsequent test is more difficult. The test will be aborted if you do not give the correct answer within 15 seconds or if you make a wrong choice three times.

With this calculator you can calculate the force, mass and acceleration from Newton's Second Law of Motion.

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.

Use this calculator to calculate the "wind chill" temperature or apparent temperature, i.e. the temperature equivalent to humans, caused by the combined effects of air temperature and wind speed

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.

With this calculator you will calculate the geometric mean, also called the power mean of the zero order.

Did you know that proper preparation is an essential factor in losing weight successfully? This test will not only help you answer the question of whether you have a chance of successful weight loss, but it will also indicate the factors that are necessary in preparation for this process.
