Question: is khz higher than hz?
Answer: One kilohertz (abbreviated "kHz") is equal to 1,000 hertz. ... Since one hertz is one cycle per second, one kilohertz is equal to 1,000 cycles per second. Kilohertz is commonly used to measure the frequencies of sound waves, since the audible spectrum of sound frequencies is between 20 Hz and 20 kHz.
