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

With this calculator you can perform a complete canonical form analysis of the quadratic function with explanations. The calculator will show you how to find the general form of a quadratic function from its canonical form. Moreover, it will determine the zeros of the function, its vertex coordinates, calculate the delta and present the product and general form of our function.

With this calculator you can quickly calculate the kinetic energy of an object. You will also calculate mass from energy and velocity and speed given kinetic energy and mass.

The PV calculator helps us to calculate the current value of an investment, i.e. the PV (present value). The PV calculator calculates the amount we need today to obtain the given value in the future after a certain number of years and calculating the interest due, assuming that they will be capitalized (added to the capital) with the specified frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) ie how much do you need today to get X in the future

Using the calculator, you can easily determine the daily need for carbohydrates, proteins and fats. As a result, the calculator will tell you how many calories and by weight you need per day and how many in each meal.

ROT47 cipher online encoder and decoder. Encrypt and decrypt any cipher created in a ROT47 cipher. You can use any shift and additionally a key for more precise text encoding.

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 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.

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

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

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.

Is the chosen weight loss plan adjusted to your needs and possibilities and will it bring the expected results?

The key to success in dietary plans is its proper selection. However, too often we choose plans that are not tailored to us, resulting in ineffectiveness and discouragement, and consequently the quick abandonment of the plan.

Use this test to find out also what factors a tailored diet plan should contain and training sessions. And it's best to apply this test to the already selected plan so as not to waste time on a wrong diet and training.

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

You can easily and quickly calculate the roots of a cubic function or cubic equation otherwise known as a third degree equation.

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.

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

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

With this calculator, you will calculate the exact tire pressure required for your bicycle tires on the front and rear wheels depending on the load, wheel size, bicycle weight, etc.

The FV calculator helps us calculate the future value of the investment. The FV calculator calculates the amount we will receive in the future after validating a given amount now for a specified number of years and after calculating the interest due, assuming that they will be capitalized (added to the capital) with a given frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) .

With this calculator you can calculate the density of the substance, i.e. specific mass. The calculator will also help to determine the mass of the substance and the volume it occupies.
