Calculation steps

1Unit scaling: 1,000.00 Hz ÷ 1000 = 1.0000 kHz; ÷ 10⁶ = 0.001000 MHz; ÷ 10⁹ = 0.000001000 GHz
2Wavelength: λ = c ÷ f = 3×10⁸ ÷ 1,000.00 = 300,000.00 m
3Period: T = 1 ÷ f = 1 ÷ 1,000.00 = 0.001000 s

Common frequency reference

Range	Application
20 Hz – 20 kHz	Audible sound
3 kHz – 300 kHz	LW/MW radio
3 MHz – 30 MHz	Shortwave (HF)
87.5 – 108 MHz	FM broadcast
300 MHz – 3 GHz	UHF / 4G / WiFi
3 GHz – 300 GHz	Microwave / 5G / satellite

Higher frequency means shorter wavelength and more information capacity, but weaker wall penetration — that is why 5G mmWave is fast yet short-ranged, and WiFi 2.4G covers farther than 5G WiFi.
