The Hz to Watts Conversion Calculator is a handy tool used to determine the power consumption of electrical devices or systems based on their voltage, current, and phase angle. This calculator simplifies the process of converting frequency (in hertz) to power (in watts) by utilizing a specific formula. Let’s delve into the details.
Formula of Hz to Watts Conversion Calculator
The formula used in the Hz to Watts Conversion Calculator is:
P = V * I * cos(φ)
Where:
- P is the power in Watts (W).
- V is the RMS voltage in volts (V).
- I is the RMS current in amperes (A).
- φ is the phase angle between voltage and current.
This formula calculates the power consumption of an electrical system, taking into account the voltage, current, and phase angle, which are essential parameters in understanding the energy usage of electrical devices.

Example of Hz to Watts Conversion Calculator
Let’s consider an example to illustrate the practical application of the Hz to Watts Conversion Calculator:
Suppose we have an electrical circuit with an RMS voltage of 120 volts (V), an RMS current of 5 amperes (A), and a phase angle of 45 degrees (φ). Using the formula mentioned earlier, we can calculate the power consumption as follows:
P = 120 * 5 * cos(45°) P ≈ 120 * 5 * 0.707 ≈ 424.26 Watts (W)
Therefore, the power consumption of the electrical circuit is approximately 424.26 Watts.
