Hertz to Kilohertz Converter
1 hertz = 0.001 kilohertz
1 hertz equals 0.001 kilohertz
How to convert hertz to kilohertz
Hertz counts complete cycles per second. This converter treats one revolution as one cycle, so 60 rpm = 1 Hz; angular frequency in radians per second would additionally involve 2π.
kHz = Hz ÷ 1000One kilohertz corresponds to 1000 hertz, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

kilohertzkHz
One thousand hertz. Used for audio sample rates and AM radio.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
