How to Convert Kilohertz to Gigahertz

Formula

To convert Kilohertz (kHz) to Gigahertz (GHz): multiply by 1.0000e-6

Step-by-Step

  1. Start with your value in Kilohertz (kHz).
  2. Multiply by 1.0000e-6 to perform the conversion.
  3. The result is your value expressed in Gigahertz (GHz).

Conversion Factor

1 kHz = 0.000001 GHz

Reverse Factor

1 GHz = 1000000 kHz

Worked Example

Convert 25 Kilohertz to Gigahertz: 25 kHz = 0.000025 GHz

About Kilohertz (kHz)

A frequency unit equal to exactly 1,000 Hz. kHz is the native band for many specific technology applications: AM (Amplitude Modulation) commercial radio broadcasting per FCC Title 47 / ITU Region 1/2/3 — Americas medium-wave broadcast band 530-1,700 kHz; CD-audio sampling rate exactly 44.1 kHz per Philips/Sony 'Red Book' specification + ANSI/SCTE standards; professional-video and film-audio sampling 48 kHz / 96 kHz / 192 kHz per AES3 / EBU 3250 / SMPTE 296 audio-engineering standards; ultrasonic medical-imaging probes 1-15 MHz with low-frequency sub-MHz transcranial Doppler at 1-2 MHz; sonar systems (low-frequency surface-ship hull-mounted 1-15 kHz, side-scan 100-500 kHz, fishfinders 50-200 kHz per NMEA 2000 / IMO standards); low-frequency RF applications (submarine VLF communication 3-30 kHz, RFID 125-134 kHz LF tags); and AM-radio carrier-frequency identification (1010 kHz, 1320 kHz, etc.). Audio engineers and broadcast-station designers work in kHz daily.

About Gigahertz (GHz)

A frequency unit equal to exactly 1,000,000,000 Hz = 10⁹ Hz. GHz is the standard reporting unit for modern semiconductor clock speeds and contemporary wireless: modern CPU clock speeds (Intel Core i9-14900K 6.0 GHz peak turbo; AMD Ryzen 9 7950X3D 5.7 GHz; Apple M3 Pro / M3 Max 4.05 GHz performance cores; the world record overclock is 9.04 GHz on liquid nitrogen with AMD FX-8350); Wi-Fi (IEEE 802.11) bands — 2.4 GHz Wi-Fi 4/5/6, 5 GHz Wi-Fi 5/6/6E, 6 GHz Wi-Fi 6E/7 with up to 320 MHz channel widths; cellular radio — sub-6 GHz 5G in 600 MHz-6 GHz spectrum, 5G mmWave 24-40 GHz per 3GPP Rel-15+ standards (n257/n258/n261); civilian + military radar (X-band 8-12 GHz, Ku-band 12-18 GHz, Ka-band 26-40 GHz for civilian satellite + automotive ADAS radar at 76-81 GHz per ETSI EN 301 091); GPS L1 carrier 1.575 GHz, L2 1.227 GHz, L5 1.176 GHz per IS-GPS-200; microwave ovens 2.45 GHz per ISM band allocation. Semiconductor datasheets, RF network-analyzer traces, and consumer wireless-device spec sheets all use GHz as the default frequency unit.
