To convert a frequency reading from megahertz (MHz) to kilohertz (kHz), you need to keep in mind the relationship between these units of measurement. One megahertz is equivalent to 1,000 kilohertz. Therefore, when you take a frequency of 3.525 MHz and convert it to kilohertz, you multiply by 1,000.

Performing the conversion:

3.525 MHz × 1000 = 3525 kHz

This calculation shows that the correct reading in kilohertz is 3525 kHz.

Understanding this conversion process is crucial in radio communication, as different devices and systems may display frequencies using various units, and knowing how to convert between them helps in proper operation and frequency management.
