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

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.

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

Vigenère cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Vigenère cipher. You can use any shift and additionally a key for more precise text encoding.

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

The calculator calculates how much energy we spend by performing selected activities within the given time. This can help you plan your daily calories burned for example.

The PV calculator helps us to calculate the current value of an investment, i.e. the PV (present value). The PV calculator calculates the amount we need today to obtain the given value in the future after a certain number of years and calculating the interest due, assuming that they will be capitalized (added to the capital) with the specified frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) ie how much do you need today to get X in the future

What would your weight be on other planets? How old would you be on another planet in the solar system? When would you have your birthday? You can check it with this calculator. You can also check what the weight of any item would be. The calculator will convert your weight and age into the weight and age you would have if you lived on Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto.

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.

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.

Bifid cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Bifid cipher. You can use any shift and additionally a key for more precise text encoding.

This calculator helps us check whether the planned investment will be profitable and whether the project should be accepted or rejected.
Thanks to the calculator, we can calculate:
NPV (Net Present Value) - sum of discounted net cash flows
PI (Profitability Index) - investment profitability
IRR (Internal Rate of Return) - internal rate of return
DPP (Discounted Payback Period) - discounted payback period
Value of discounted net cash flow for each period.

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.

With the COSINE Trigonometric Calculator you can calculate the values of any cosine function. In addition to the response results, the calculator will also plot the selected function. You can choose one of the preset functions, e.g. cosine, cos ² - cosine square, arccos - arccosine, cosh - hyperbolic cosine, arcosh - function inverse to cosh, you can also enter your own function, e.g. cos(x ) * cos(x) * cos(x) for cos³(x), cos(2x), cos(x+3), cos(x^2) etc.

With this calculator you can perform a complete canonical form analysis of the quadratic function with explanations. The calculator will show you how to find the general form of a quadratic function from its canonical form. Moreover, it will determine the zeros of the function, its vertex coordinates, calculate the delta and present the product and general form of our function.

Use this calculator to calculate the molecular weight of gas.
