With this calculator you can calculate the force, mass and acceleration from Newton's Second Law of Motion.

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.

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.

Regular polygon calculator will help you calculate the diagonals of any regular polygon, side length, height, area, perimeter and radius of the circumscribed circle and the radius of the circle inscribed in a regular polygon.

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.

With the Langevin trigonometric function calculator you can calculate the values of the function. In addition to the response results, the calculator will also plot the selected function. You can choose a ready function, e.g. L(x) or enter your own function, e.g. L(x^2), L(x+3) etc.

Did you know that proper preparation is an essential factor in losing weight successfully? This test will not only help you answer the question of whether you have a chance of successful weight loss, but it will also indicate the factors that are necessary in preparation for this process.

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

Thanks to the calculator you can calculate the number of letters, the number of words, the number of characters and the number of paragraphs in any text.

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.

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.

Using this calculator, you will calculate the pulse duration of the output pulse of the NE555 IC in monostable or astable mode of operation.

Using this calculator, you can calculate the total volume of the solution after dilution and the volume of solvent added during dilution.

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.

With this calculator you will calculate the mean square or arithmetic mean of the squares also known as the power mean of the second order.

With this calculator you can calculate voltage drops for single-phase and three-phase AC circuits calculated from the rated current. You will also calculate wire length, wire diameter, wire cross-sectional area, voltage or current.

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.
