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

Using the calculator, you will calculate the resting metabolic rate (RMR) and the amount of calories needed to supplement, i.e. burned by the body while resting.

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.

Online calculator calculates the mode of series of distributing class intervals. You learn how to find the Modal value for a grouped data with different intervals between the data classes.

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 statistical calculator, you will learn how to calculate a linear regression step by step.

With this calculator you will calculate the voltage drops for single-phase and three-phase AC circuits calculated from active power. You will also calculate cable length, conductor diameter, conductor cross-sectional area, phase or line voltage or active power.

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).

Height calculator will help you calculate what height your child will have in the future, ie when it stops growing. Predicted Adult Height

Using this calculator you can calculate the molar concentration of the solution, ie the number of moles of a given chemical substance that contains 1 liter of solution.

With the Fractions Calculator, you can add any two mixed numbers or proper and improper fractions.
Fractions Calculator will show you the result of operations on fractions step by step and will give you explanations of the operations performed to add fractions. You will learn how to simplify fractions, how to find a common denominator, how to find the least common multiple and the greatest common divisor.

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

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.

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 life expectancy and health age calculator will let you know your life expectancy. First of all, it will make you aware of what factors affect your life expectancy and your real age according to your health.

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.

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

You will calculate with fairly high accuracy the likelihood of your baby having a particular blood group.

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.
