Hz to kW Calculator

Formula

To calculate the Power Output ( $P$ ):

$P = \frac{V \times I \times PF \times \sqrt{3} \times f}{1000}$

Where:

$P$ is the Power Output (kW)
$V$ is the Voltage (volts)
$I$ is the Current (amperes)
$PF$ is the Power Factor (unitless, between 0 and 1)
$\sqrt{3}$ is the square root of 3, a constant in three-phase power calculations
$f$ is the Frequency (Hz)

What is Hz to kW?

Hz (Hertz) and kW (Kilowatt) are two different units used in measuring different aspects of electricity. Hz is a unit of frequency, indicating the number of cycles per second in an alternating current (AC) electrical signal. On the other hand, kW is a unit of power, indicating the rate at which energy is used or produced. Therefore, Hz to kW is not a direct conversion as they measure different aspects of electricity.

Example Calculation 1

Let's assume the following values:

Voltage ( $V$ ) = 400 volts
Current ( $I$ ) = 50 amperes
Power Factor ( $PF$ ) = 0.8
Frequency ( $f$ ) = 60 Hz

Using the formula:

$P = \frac{400 \times 50 \times 0.8 \times \sqrt{3} \times 60}{1000} \approx 1662.8$

The Power Output is approximately 1662.8 kW.

Example Calculation 2

Let's assume the following values:

Voltage ( $V$ ) = 230 volts
Current ( $I$ ) = 30 amperes
Power Factor ( $PF$ ) = 0.9
Frequency ( $f$ ) = 50 Hz

Using the formula:

$P = \frac{230 \times 30 \times 0.9 \times \sqrt{3} \times 50}{1000} \approx 537.8$

The Power Output is approximately 537.8 kW.
