How the Frequency Converter Works

1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly

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.

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

FAQs

How many hertz are in one megahertz?

Exactly 1,000,000 — the SI prefixes are powers of ten, so a 2.4 GHz Wi-Fi channel oscillates 2,400,000,000 times per second. No rounding ever enters these conversions. On this frequency unit converter page the head rule is 1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly.

Is angular frequency the same as hertz?

No. Ordinary frequency f counts cycles per second (Hz), while angular frequency ω = 2πf counts radians per second. A 50 Hz motor spins at ω ≈ 314.16 rad/s — mixing the two breaks every vibration formula. On this frequency unit converter page the head rule is 1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly.

Which units does this frequency unit converter cover?

It converts Hz, kHz & MHz plus the wider frequency unit family — pick any pair after typing your value. Every factor shown is the international definition, e.g. 1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly.

How do I use the frequency unit converter?

Type a value, choose the unit you already have, choose the unit you want, and the converted result appears instantly with the exact factor applied.

Is the frequency unit conversion accurate?

Yes — each factor is the fixed international definition (1 MHz = 1,000,000 Hz and 1 GHz = 1000 MHz exactly), so results are exact up to the decimals displayed. Only rounding for display changes the figure you see.
