“Hertz” (Hz) and “terahertz” (THz) are units of frequency, specifically how often a periodic event occurs within a second. They are named in honor of Heinrich Hertz, a German physicist who made significant contributions to the understanding of electromagnetic waves.

## Hertz (Hz)

One hertz means that an event repeats once per second. For example, if a pendulum swings back and forth once every second, its frequency is 1 Hz.

## Terahertz (THz)

Terahertz is a multiple of the unit hertz and represents one trillion cycles per second. 1 THz = 1,000,000,000,000 Hz or 10^{12} Hz.

### How to convert hertz to terahertz

1Hz = 10^{-12}THz

or

1THz = 10^{12}Hz

#### Hertz to terahertz formula

f(THz) = f(Hz) / 1012

Example – Convert 300 hertz to terahertz

Ans. f_{(THz)} = 300Hz / 10^{12} = 3×10^{-10}THz

## FAQs on Hz to THz conversion

### What is 1 THz equal to?

1 THz (Terahertz) is equal to 1 trillion hertz or 10^12 Hz.

### What is the conversion of 1 Hz?

1 Hz stands for one cycle per second and is the base unit of frequency in the International System of Units (SI).

### What is the wavelength of 1 THz?

The wavelength (λ) of a frequency is inversely proportional to its frequency and can be found using the formula: λ = c / f, where c is the speed of light (~299,792,458 meters per second). For 1 THz, the wavelength is approximately 0.3 millimeters.

### What is the relationship between hertz and terahertz?

Terahertz (THz) is a multiple of the unit hertz (Hz). 1 Terahertz is equal to 1 trillion hertz.

### Is Hz smaller than THz?

Yes, 1 Hz is much smaller than 1 THz. 1 THz is equivalent to 10^12 Hz.

### What is 400 THz to 700 THz?

400 THz to 700 THz refers to a range of frequencies. This range is significant because it corresponds to the visible light spectrum.

### What is the wavelength of 10 THz?

Using the formula λ = c / f, where c is the speed of light, the wavelength for 10 THz is approximately 0.03 millimeters or 30 micrometers.

### What is the SI unit for THz?

The SI unit for measuring frequency is the hertz (Hz). Terahertz (THz) is a derived metric prefix which stands for 10^12 hertz.
