How the Frequency Converter Works
This frequency unit converter routes every input through exact definitions — 1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly. Enter a value, pick the source and target units, and the result appears instantly with the factor applied shown beside it. Hertz, kilohertz, megahertz and gigahertz count cycles per second in clean 1000-step SI ladders — the natural units of radio, processors, sound and light. Every step is exact: 1 kHz = 1000 Hz, 1 MHz = 1,000,000 Hz, 1 GHz = 1,000,000,000 Hz, so conversions introduce zero uncertainty beyond display rounding. A mini table of the head factor makes spot-checks immediate: 1 MHz = 1,000,000 Hz; 5 MHz = 5,000,000 Hz; 10 MHz = 10,000,000 Hz; 50 MHz = 50,000,000 Hz; 100 MHz = 100,000,000 Hz. Scale anchors: mains power hums at 50 or 60 Hz, FM radio lives near 100 MHz, Wi-Fi at 2.4 or 5 GHz, and visible light approaches 400–790 THz.

Reading audio sample rates and tone frequencies
Tips
- 1
kHz → Hz: ×1000; MHz → kHz: ×1000 — pure powers of ten
- 2
Radio shorthand: "2m band" ≈ 145 MHz; "70 cm" ≈ 435 MHz
- 3
Audio: A4 = 440 Hz exactly by modern concert convention
- 4
ω = 2πf converts every vibration table to radians
Common Mistakes
Mixing Hz (cycles) with rad/s (angular) without the 2π factor
Counting kHz as 1024 Hz — frequency is decimal, unlike bytes
Quoting bandwidth in Mbps where MHz is meant on radio specs
