Unit definitions

Hertz

The hertz is the SI unit of frequency. It is defined as the number of cycles in one second ($1\ \text{Hz} = 1\ \text{s}^{-1}$).

Kilohertz

$10^{3} \ \text{Hz}$ is a kilohertz.

How to convert Hertz to Kilohertz

$$\text{Frequency}_{\text{kHz}} = \frac{\text{Frequency}_{\text{Hz}}}{{10}^{3}}$$

Examples

Example 1

Convert $20.0\ \text{Hz}$ to $\text{kHz}$.

$$\text{Frequency}_{\text{kHz}} = \frac{20.0}{{10}^{3}}$$

$$\text{Frequency}_{\text{kHz}} = 0.02$$

$$\therefore \ 20.0\ \text{Hz} = 0.02 \ \text{kHz}$$

Example 2

Convert $75.0\ \text{Hz}$ to $\text{kHz}$.

$$\text{Frequency}_{\text{kHz}} = \frac{75.0}{{10}^{3}}$$

$$\text{Frequency}_{\text{kHz}} = 0.075$$

$$\therefore \ 75.0\ \text{Hz} = 0.075 \ \text{kHz}$$

Example 3

Convert $120.0\ \text{Hz}$ to $\text{kHz}$.

$$\text{Frequency}_{\text{kHz}} = \frac{120.0}{{10}^{3}}$$

$$\text{Frequency}_{\text{kHz}} = 0.12$$

$$\therefore \ 120.0\ \text{Hz} = 0.12 \ \text{kHz}$$

Example 4

Convert $130.0\ \text{Hz}$ to $\text{kHz}$.

$$\text{Frequency}_{\text{kHz}} = \frac{130.0}{{10}^{3}}$$

$$\text{Frequency}_{\text{kHz}} = 0.13$$

$$\therefore \ 130.0\ \text{Hz} = 0.13 \ \text{kHz}$$

Example 5

Convert $165.0\ \text{Hz}$ to $\text{kHz}$.

$$\text{Frequency}_{\text{kHz}} = \frac{165.0}{{10}^{3}}$$

$$\text{Frequency}_{\text{kHz}} = 0.165$$

$$\therefore \ 165.0\ \text{Hz} = 0.165 \ \text{kHz}$$
