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

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.

Thanks to this calculator, you can easily calculate the cost and the amount of paint needed to paint any room.

Use this calculator to calculate the molecular weight of gas.

With the Hubbert Curve Calculator you will calculate the 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. hubb(x) or enter your own function, e.g. hubb(x^2), hubb(x+3), etc.

The calculator will calculate the estimated number of heartbeats and breaths you have given since birth.

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

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.

The CAPM calculator can be used to calculate the cost of equity, to evaluate the investment effectiveness of collective investment funds (open-end investment funds, pension funds, etc.), to study the efficiency of the stock market, etc.
The CAPM model allows to illustrate the relationship between the incurred systematic risk, otherwise known as market or non-diversifiable risk, and the expected rate of return.

The CAPM calculator in the form of CML allows you to calculate the expected rate of return from the so-called the effective portfolio (on the border of Markowitz's effective portfolios).

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 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.

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.

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

How to convert a dog's age to human age? How old is a dog in human years? How long will my dog live? Dog Age Calculator will help you with these and many other questions.

With this calculator you can calculate the HB hardness or the hardness of metals based on the Brinell hardness test.

The calculator is used to calculate the coverage of bills by profit before paying off the tax bill.

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

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

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.

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