1 Kilohertz = 0.001 Megahertz
Key Formulas
Hertz → Kilohertz
kHz = Hz × 0.001Kilohertz → Hertz
Hz = kHz × 1000Megahertz → Gigahertz
GHz = MHz × 0.001Gigahertz → Megahertz
MHz = GHz × 1000Formula
MHz = kHz ÷ 1,000AM radio broadcasts in kHz (540–1700 kHz), FM radio in MHz (87.5–108 MHz), and audio sample rates straddle both — 44,100 Hz is 44.1 kHz or 0.0441 MHz. When you work across these bands, converting kHz to MHz keeps the numbers readable. A shortwave station at 9,600 kHz is 9.6 MHz; an audio engineer setting a 48,000 Hz sample rate is working at 48 kHz = 0.048 MHz. Divide kHz by 1,000 to move to MHz.

Frequently Asked Questions
Real-World Examples
FM radio station '101.5 FM' broadcasts at 101,500 kHz = 101.5 MHz. FM stations are always identified by their MHz frequency.
101500 kHz = 101.5 MHz
Shortwave radio at 9,600 kHz = 9.6 MHz. International broadcasting services use the 9–10 MHz (9,000–10,000 kHz) shortwave band.
9600 kHz = 9.6 MHz
1 MHz = 1,000 kHz exactly. A 1 MHz crystal oscillator, common in clocks and timers, runs at 1,000 kilohertz.
1000 kHz = 1 MHz
CD audio sample rate at 44,100 Hz = 44.1 kHz = 0.0441 MHz. Digital audio specs often switch between Hz, kHz, and MHz depending on context.
44100 kHz = 44.1 MHz
