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.

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 can calculate the molecular weight of any chemical compound.

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

Bacon cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Bacon cipher.

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.

This calculator is a complete tool to calculate the heat loss of your home Whit this calculator, we will find out what the heat losses are, e.g. through the ceiling, external walls, windows, floor in each room of our house, depending on the type of building material, number of layers, insulation and external temperature.

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.

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.

Use the Ishihara test to check if you suffer from color blindness, to what extent your defect is Protanopia or Deuteranopia, or maybe just insufficient differentiation between red and green shades. As a result, in addition to the diagnosis, you will have the opportunity to check how each of the Ishihara plates is seen by people with various visual impairments, and if you have a defect, they will allow you to see what is on the plates.

With this calculator you will calculate the geometric mean, also called the power mean of the zero order.

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

Calculate the diagonals of a concave deltoid, kite, side lengths, surface area, perimeter and radius of the inscribed circle. Each size can be calculated using many formulas, just indicate what data we have.

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.

Use this calculator to calculate the "wind chill" temperature or apparent temperature, i.e. the temperature equivalent to humans, caused by the combined effects of air temperature and wind speed

Calculate how much you spend smoking, so how much you could save after quitting smoking.

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

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

This calculator helps us check whether the planned investment will be profitable and whether the project should be accepted or rejected.
Thanks to the calculator, we can calculate:
NPV (Net Present Value) - sum of discounted net cash flows
PI (Profitability Index) - investment profitability
IRR (Internal Rate of Return) - internal rate of return
DPP (Discounted Payback Period) - discounted payback period
Value of discounted net cash flow for each period.
