The WHR calculator calculates the ratio of waist circumference to hip circumference.
Thanks to the Talia-Hips calculator, we will find out what type of obesity we have, what is the risk of hypertension, coronary diseases, stroke, atherosclerosis and diabetes, and we will learn the average standard WHR for our gender and age.

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.

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 calculator in the form of SML allows you to calculate the expected rate of return on all portfolios, not only effective ones, as well as individual stock market shares.

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.

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.

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

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

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

The DFL Finacial Leverage Calculator will help us calculate how sensitive the cash flow is to changes in operating profit.
With the DOL Operating Leverage Calculator, we will calculate how sensitive operating revenues are to changes in sales. The DTL Total Leverage Calculator will help us calculate the profit sensitivity to sales growth.

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.

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.

With this statistical calculator, you will learn how to calculate the arithmetic mean of a distribution point series (grouped data).

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.

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.

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.

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.
