With this calculator, you can calculate the resistance of the cable, knowing the material it is made of. You can also calculate the length of the conductor and the conductor diameter or the conductor cross-section area.

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.

Heptagon calculator will help you calculate the long diagonal of the heptagon, the short diagonal of the heptagon, the side length, heights, area of the heptagon, the radius of the circumscribed circle and the radius of the circle inscribed in a regular heptagon.

With this calculator you can quickly calculate the centripetal force. You will also calculate the mass of the body from velocity, radius and force, the radius of the circle given the mass of the body, the force and speed and the speed of the object moving in the circle given the given force, mass and radius.

The calculator is used to calculate the coverage of bills by profit before paying off the tax bill.

Thanks to the calculator, you can easily calculate the amount of calories you burn every day. There are over 600 different activities available, from which you can choose those that were or will be performed on a given day and set the duration for each selected activity.

As a result, the calculator will provide the total duration of all activities, the sum of calories burned and the number of calories consumed for each activity separately, including the time of its execution. The calculator also tells you how many hours you need to constantly perform a given activity to lose weight by about 0.5 kg, taking into account your weight.

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.

Use this calculator to calculate the molecular weight of gas.

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.

With the help of the calculator you will calculate the determinant of the fourth degree matrix by the Laplace Expansion method. You will learn step by step how the calculations are performed and we will get explanations of each action. A useful tool for learning, consolidating, checking your own calculations and understanding the Laplace method.

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

Rail Fence, Zig-Zag cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Rail Fence, Zig-Zag cipher.

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

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.

With this online function graph plotter, you can draw any function. On one graph you can draw any three functions and compare their parameters. You can create graphs for many equations and functions.

Using the calculator, we will calculate the water lost from the body and the percentage of weight loss after the exercises.

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

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

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.
