Which is equal to 3.525 MHz?

In radio frequencies, 'kilo-' (kHz) stands for one thousand hertz, and 'mega-' (MHz) stands for one million hertz. Because a million is one thousand thousands, there are exactly 1,000 kilohertz in one megahertz. To convert a frequency from megahertz (MHz) to kilohertz (kHz), you multiply the value by 1,000. Moving the decimal point three places to the right transforms 3.525 MHz directly into 3525 kHz. The distractors test your ability to convert units correctly. Dividing instead of multiplying, or shifting the decimal by the wrong number of places, leads to incorrect answers like 35.25 kHz or 0.003525 kHz.
