About This Conversion
Kilohertz to hertz multiplies by 1,000. Audio work needs it constantly, because sample rates are quoted in kilohertz while filter frequencies, tunings and hearing ranges are given in hertz.
The anchors are worth knowing: human hearing spans roughly 20 Hz to 20 kHz, CD audio samples at 44.1 kHz, video audio at 48 kHz, and concert A is 440 Hz. The 32.768 kHz in the table is the quartz crystal in nearly every watch and real-time clock, chosen because 32,768 is 2¹⁵ and divides down to exactly one pulse per second.
Frequently Asked Questions
How many Hz are in a kHz?
One kilohertz is 1,000 hertz.
What is 44.1 kHz in Hz?
44,100 Hz, the CD audio sample rate.
What is the range of human hearing in Hz?
Roughly 20 Hz to 20,000 Hz, narrowing at the top end with age.
Why is 32.768 kHz used in clocks?
It is 2¹⁵ Hz, so fifteen halvings give exactly one pulse per second.
