With the converter, you can quickly translate any sentence into Morse code and vice versa. You can listen to the translated code, see it thanks to the light signals or, using the phone, feel it through vibration. Morse code is used nowadays mainly in amateur radio, it is also useful in many other areas of life.

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

Are your hair falling out, are you starting to go bald? Use this calculator and check the probability and age at which you may be at risk of total hair loss.

The caloric demand calculator will help you create the right diet. It will answer the question of what is our daily calorie requirement and how much daily do we need to consume carbohydrates, proteins and fats to gain weight or lose weight by a given weight within a certain period of time.
We have a choice of several of the most popular formulas for calculating the basal metabolic rate. As a result, we will also get a seven-day alternating caloric cycle, thanks to which, with long-term diets, we can "cheat" the body by consuming different caloric values a day while maintaining a weekly diet.

You can calculate any system of linear equations, both homogeneous and heterogeneous with any number of unknowns Using the Inverse of a Matrix method.

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

With this calculator, you can easily calculate the cost and amount of wallpaper needed to make any room.

Thanks to the calculator, you can quickly and easily calculate how much money you will accumulate in a given period by putting a monthly fixed amount on your account for a specified period of time, giving the annual interest rate.

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.

You can calculate any system of linear equations, both homogeneous and heterogeneous with any number of unknowns by Gauss-Crout elimination method.

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 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 coverage of bills by profit before paying off the tax bill.

Hexagon calculator will help you calculate the long diagonal of the hexagon, the short diagonal of the hexagon, the side length, height, area of the hexagon, the radius of the circumscribed circle and the radius of the circle inscribed in a regular hexagon.
