Which is equal to 3.525 MHz?

The prefix 'mega' (M) means one million (10^6), while the prefix 'kilo' (k) means one thousand (10^3). Because one million is a thousand times larger than one thousand, one Megahertz (MHz) is equivalent to 1000 kilohertz (kHz). To convert a frequency from MHz to kHz, you must multiply the MHz value by 1000. Mathematically, this is done by moving the decimal point three places to the right. Multiplying 3.525 by 1000 results in exactly 3525 kHz. Amateur radio operators constantly switch between MHz and kHz when reading frequency charts, band plans, or adjusting transceivers. Distractors like 0.003525 kHz occur if you mistakenly divide by 1000 instead of multiplying.
