With this statistical calculator You can easily calculate standard deviation, variance of standard deviation, population standard deviation, variance of population standard deviation and arithmetic mean. With this data analysis tool, you will see the calculations performed step by step along with the formulas used.

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

The Body Fat percentage calculator will help you calculate the amount of fat stored in your body. It uses a method of measuring skin folds in three different places on the body.

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, we will find out what ventilation efficiency should have depending on the size, height and type of room, e.g. in the kitchen, bathroom or toilet. The ventilation calculator will help us choose the right fan for the selected room, e.g. it will facilitate the selection of the hood for the kitchen.

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.

With the CATENARY Trigonometric Function Calculator, you can calculate catenary chain curve values. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. cat(?#X) where for ? you will substitute e.g. 2 for catenary two which will be equal to 2*cosh(x/2) or enter your own function e.g. cat(2#x^2) for 2*cosh((x^2)/2), cat(2#x+3) for 2*cosh((x+3)/2) etc.

Pentagon calculator will help you calculate the long diagonal of the pentagon, the medium diagonal of the pentagon, the shorter diagonal of the pentagon, the side length, height, area of the pentagon, circumference and radius of the circumscribed circle and the radius of the circle inscribed in the regular pentagon.

With the GUDERMANN trigonometric function calculator you can calculate the values of the hyperbolic amplitude. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. gd(x) or arcgd(x) as the inverse of the Gudermann function, or enter your own function, e.g. gd(x^2), gd(x+3), etc.

Rectangular trapezoid calculator will help you calculate the long diagonal of the trapezoid, the short diagonal of the trapezoid, the side length, height, area and perimeter of the trapezoid.

Playfair cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Playfair cipher.

With this calculator you can calculate the density of the substance, i.e. specific mass. The calculator will also help to determine the mass of the substance and the volume it occupies.

Regular polygon calculator will help you calculate the diagonals of any regular polygon, side length, height, area, perimeter and radius of the circumscribed circle and the radius of the circle inscribed in a regular polygon.

The calculator helps you to calculate the present value of money (PV) and the future value of money (FV) in time.

With this statistical calculator, you will learn how to calculate the median of an interval distributive series from grouped data.

Using this calculator, you can calculate the volume percent concentration, also called the volume percentage of chemicals in mixtures and solutions.

The online calculator calculates the median called the median value or the average value, the most common numbers in the given set, i.e. the mode, by examining whether it exists, the arithmetic mean and sorts the data in ascending order.

Using this calculator you can calculate the percentage concentration, also called the percentage by weight of chemical substances in mixtures and solutions.
