Gigahertz to Megahertz
One gigahertz equals 1000 megahertz.
Megahertz = gigahertz × 1000

Frequency Reference Guide
Frequency Unit Relationships
1 kHz = 1,000 Hz
1 MHz = 1,000 kHz = 1,000,000 Hz
1 GHz = 1,000 MHz = 1,000,000,000 Hz
1 THz = 1,000 GHz = 10¹² Hz
1 RPM = 1/60 Hz ≈ 0.0167 Hz
1 RPS = 1 Hz
1 rad/s = 1/(2π) Hz ≈ 0.159 Hz
Angular frequency: ω = 2πf
Frequency Spectrum Applications
Audio Range: 20 Hz - 20 kHz (human hearing)
Radio Waves: 3 kHz - 300 GHz
AM Radio: 535 - 1605 kHz
FM Radio: 88 - 108 MHz
WiFi 2.4GHz: 2.4 - 2.485 GHz
WiFi 5GHz: 5.15 - 5.85 GHz
Microwave: 300 MHz - 300 GHz
Visible Light: ~400 - 800 THz
Technical Applications
CPU Clock: 1-5 GHz (modern processors)
AC Power: 50-60 Hz (mains electricity)
Musical Note A4: 440 Hz (concert pitch)
Ultrasound: >20 kHz (medical imaging)
Radar: 1-100 GHz (various bands)
X-rays: 30 PHz - 30 EHz (10¹⁶-10¹⁹ Hz)
Conversion Tips
• Period (T) and frequency (f) are reciprocals: T = 1/f
• Higher frequency = shorter wavelength (for electromagnetic waves)
• Angular frequency (ω) = 2π × frequency (f)
• Use scientific notation for very large or small frequencies

About This Conversion
Gigahertz to megahertz multiplies by 1,000, the step needed when a device is specified in GHz but a configuration screen, a regulatory table or a spectrum chart works in MHz.
Processor clocks live in the same range and convert identically: a 3.6 GHz CPU runs at 3,600 MHz, or 3.6 billion cycles per second. Clock speed alone stopped predicting performance a long time ago, but it remains the number quoted, and it is still just a frequency.
