How can "100,000 cycles per second" be expressed in kilohertz?

To convert "100,000 cycles per second" into kilohertz, it's essential to understand the relationship between cycles, hertz, and kilohertz. Hertz (Hz) is the unit of frequency that denotes the number of cycles per second. One kilohertz (kHz) equals 1,000 hertz. Therefore, to convert cycles per second into kilohertz, you can divide the number of cycles (in hertz) by 1,000.

In this case, to find how many kilohertz 100,000 cycles per second equals, you would perform the following calculation:

100,000 cycles per second ÷ 1,000 = 100 kilohertz.

This means that 100,000 cycles per second is equivalent to 100 kilohertz, making this the correct answer. Understanding how these units relate to one another is crucial for interpreting frequency measurements correctly in various applications, including Nondestructive Testing (NDT) contexts.
