Which is equal to 1,500,000 hertz?

The metric prefix 'kilo-' stands for one thousand (1,000), while 'mega-' stands for one million (1,000,000). These prefixes save us from having to write out long strings of zeroes. To convert hertz to kilohertz, you divide the raw number by 1,000. Dividing 1,500,000 Hz by 1,000 leaves 1,500 kHz. If you were converting to megahertz (MHz), you would divide by one million, resulting in 1.5 MHz. Distractors like 1500 MHz or 15 GHz represent massive decimal shifts in the wrong direction, describing frequencies far higher than 1.5 million hertz.
