About Megahertz (MHz)
A frequency unit equal to exactly 1,000,000 Hz = 10⁶ Hz. MHz is the dominant band for commercial broadcasting, two-way-radio, and consumer wireless: FM (Frequency Modulation) commercial radio band 88-108 MHz per FCC Part 73; VHF television broadcast band 54-216 MHz (now repacked post-incentive auction); UHF TV 470-608 MHz; amateur (ham) radio 2 m band 144-148 MHz + 70 cm band 420-450 MHz per FCC Part 97; LMR (Land Mobile Radio) for public-safety + first-responders 150-174 MHz VHF and 450-470 MHz UHF per APCO P25 + DMR / NXDN / TETRA standards; cellular baseband frequencies in the original 800 MHz AMPS band and the later 900-960 MHz / 1700-2100 MHz LTE bands; older microprocessor clock speeds (Intel 8086 ~5 MHz; original Pentium 60-200 MHz; Pentium III 450 MHz - 1 GHz). Spectrum allocation by regulators (FCC, Ofcom, ETSI, ITU-R) is organized primarily in MHz bands in regulatory documents.
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.
