02 / WORKED EXAMPLES

  • Wi-Fi band: 2.4 GHz to hertz

    A 2.4 GHz Wi-Fi channel is 2.4 × 109 = 2,400,000,000 Hz, which is the same as 2,400 MHz. Multiply gigahertz by one billion to reach hertz.

  • CPU clock: 3.2 GHz to megahertz

    A 3.2 GHz processor clock is 3.2 × 103 = 3,200 MHz. Each step up the prefix ladder (kHz → MHz → GHz) is a factor of one thousand.

  • Motor speed: 3,000 rpm to hertz

    Revolutions per minute become hertz by dividing by 60: 3,000 ÷ 60 = 50 Hz. So a 3,000 rpm shaft turns at 50 cycles per second.

How it works

Frequency measures how many cycles or events happen each second. The SI unit is the hertz (Hz), defined as one cycle per second. Every larger unit is a decimal power of the hertz: 1 kHz = 10^3 Hz, 1 MHz = 10^6 Hz and 1 GHz = 10^9 Hz. Revolutions per minute (rpm) counts cycles per minute, so 1 rpm = 1/60 Hz. The converter first normalises your input to hertz using the exact NIST SP 811 decimal factors, then converts to the target unit, so one small checkable factor table covers every from/to pair without compounding rounding. Same-unit conversions return the input exactly.

Assumptions & limits

  • Conversion factors are the exact decimal values published in NIST SP 811.
  • The rpm to hertz conversion uses the exact 60 seconds-per-minute definition (1 rpm = 1/60 Hz).
  • Only the displayed value is rounded; the calculation keeps full precision.

FAQ

How many hertz are in a megahertz?
One megahertz equals 1,000,000 hertz (1 MHz = 10^6 Hz). For reference, 1 kHz = 1,000 Hz and 1 GHz = 1,000,000,000 Hz, because each prefix step is a factor of one thousand.
What is 2.4 GHz in hertz?
2.4 GHz equals 2,400,000,000 Hz, which is also 2,400 MHz. This is the band used by many Wi-Fi and Bluetooth devices, so the same figure often appears written as 2.4 GHz or 2400 MHz.
Is hertz the same as megahertz?
No. A megahertz is one million hertz (1 MHz = 1,000,000 Hz), so the two differ by a factor of a million. A 100 MHz value is 100,000,000 Hz, not 100 Hz.
How do I convert RPM to hertz?
Divide revolutions per minute by 60, because there are 60 seconds in a minute. For example, 3,000 rpm = 3000 / 60 = 50 Hz, and 1,800 rpm = 30 Hz. To go the other way, multiply hertz by 60.
What frequency is mains electricity?
Mains alternating current runs at 50 Hz across most of the world and 60 Hz in North America and parts of South America and Asia. That is why appliance and motor ratings sometimes list both 50/60 Hz.
Why convert through a base unit?
Normalising every unit to hertz first means one small, checkable factor table covers every from/to pair without compounding rounding across intermediate steps.
