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.

Using this calculator, you can calculate the volume percent concentration, also called the volume percentage of chemicals in mixtures and solutions.

Triangle calculator will help you calculate the area, perimeter, sides, height, angles of any triangle, right triangle and equilateral.

The calculator is used to calculate the ventilation capacity in an attic or loft for the minimum, normal and extreme thermal conditions of the environment depending on the area and height of the room and the roof pitch. The fan removes warm air from the room and should be mounted at the highest possible point for the best efficiency.

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

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.

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.

Parallelogram calculator will help you calculate the long diagonal of the parallelogram, the short diagonal of the parallelogram, the side length, heights, area of the parallelogram.

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.

Octagon calculator will help you calculate the long diagonal of the octagon, the medium diagonal of the octagon, the shorter diagonal of the octagon, the side length, height, area of the octagon, circumference and radius of the circumscribed circle and the radius of the circle inscribed in the regular octagon.

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 this calculator you can calculate the gravitational acceleration of a body pulled by another body. 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.

Using this calculator you can calculate the percentage concentration, also called the percentage by weight of chemical substances in mixtures and solutions.

This financial calculator will help you calculate the purchase or sale price of Treasury bills, the amount and the annual discount rate.

With the Hubbert Curve Calculator you will calculate the 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. hubb(x) or enter your own function, e.g. hubb(x^2), hubb(x+3), etc.

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).

Thanks to the calculator, you can calculate the partial volume according to Daltons law.

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