Hz to Watts Conversion Calculator – Convert Hertz (Hz) to Watts (W)

This Hz to watts calculator is used to convert frequency Hertz to power in Watts using P = V × I × cos(φ) formula.

• 50 Hz and uses 220V and 5A: P = V × I = 220V × 5A = 1100W
• 60 Hz with 120V and 10A: P = V × I = 120V × 10A = 1200W

Hertz (Hz) is a unit of frequency, representing the number of cycles per second in a periodic phenomenon. In electrical systems, it typically refers to the frequency of alternating current (AC).

Watts (W), on the other hand, is a unit of power, measuring the rate at which energy is transferred or consumed.

Hz to Watts Conversion Formula

For DC circuits:

P = V × I

Where:

• P = Power (Watts)
• V = Voltage (Volts)
• I = Current (Amperes)

For electrical systems (AC power):

P = V I cos(φ)

Where:

• P is Power in Watts
• V is Voltage in Volts
• I is Current in Amperes
• cos(φ) is the power factor

For rotating mechanical systems:

P = 2π τ f

Where:

• P is Power in Watts
• τ is Torque in Newton-meters
• f is Frequency in Hz

In an AC circuit with 120V, 10A, and a power factor of 0.8, operating at 60 Hz:

P = 120V 10A 0.8 = 960 Watts

Note that the frequency (60 Hz) isn’t directly used in this calculation but is a characteristic of the AC system.

How do you convert Hz to watts?

In AC electrical systems:

• Determine the voltage (V) and current (I)
• Find out the power factor (cos(φ))
• Use the formula: P = V I cos(φ)

In rotating mechanical systems:

• Measure the torque (τ)
• Use the formula: P = 2π τ f

For a motor with a torque of 10 Nm rotating at 3000 RPM (50 Hz):

P = 2π 10 Nm 50 Hz = 3141.59 Watts

How many watts are in 50 Hz?

A small appliance circuit: 220V, 5A: P = 220V 5A 1 (assuming power factor of 1) = 1100 Watts

An industrial power line: 11000V, 100A: P = 11000V 100A 0.9 (assuming power factor of 0.9) = 990,000 Watts

Both systems operate at 50 Hz, but their power outputs are vastly different.
