Converting megahertz (MHz) to kilohertz (kHz) is straightforward: multiply the frequency value in megahertz by 1,000. This is because 1 MHz equals 1,000 kHz. For example, to convert 5 MHz to kHz, calculate 5 × 1,000, resulting in 5,000 kHz. This conversion is essential in fields like telecommunications and audio engineering, where precise frequency measurements are crucial. Utilizing online calculators can simplify this process, ensuring accurate and efficient conversions.
