The calculator will also help to calculate the distance between the centers of the attracting bodies and the mass of the body producing the gravitational field and attracting the body for which the gravitational acceleration is given.

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

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 cone calculator will help you calculate the volume of the cone, the total area of the cone, the side area of the cone, the base area of the cone, the generatrix length and the radius of the cone base, and the volume of the sphere described on the cone.

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.
