If a frequency readout calibrated in megahertz shows a reading of 3.525 MHz, what would it show if it were calibrated in kilohertz?

When converting frequencies between megahertz (MHz) and kilohertz (kHz), it’s essential to remember the relationships between these units. One megahertz is equal to 1,000 kilohertz. Therefore, to convert a frequency from megahertz to kilohertz, you multiply the megahertz value by 1,000.

In this case, the given frequency is 3.525 MHz. To convert this to kilohertz, you take:

3.525 MHz * 1,000 = 3,525 kHz.

Thus, when calibrated in kilohertz, a frequency of 3.525 MHz displays as 3,525 kHz. This understanding reflects a correct grasp of unit conversion in radio communications, which is crucial for operating ham radio equipment.
