Some facts

  • Frequency is physical quantity defining number of cycles (events occurring periodically) per time unit.
  • The basic frequency unit in SI system is one Hz (hertz). One hertz corresponds to the frequency of one cycle per second:
    1Hz=1s1 Hz = \frac{1}{s}

  • Frequency is usually indicated by a lower case letter f or greek letter ν\nu (nu).
  • To calculate the frequency of an event directly from the definition, use the following formula:
    f=ntf = \frac{n}{t}
    where:
    • f - frequency,
    • n - number of recorded events (cycles),
    • t - measurement time.
  • We can find frequency in many everyday areas of life, e.g.
    • The musical note of "A" is used as a standard for tuning musical instrument. It's frequency is 440 Hz. In terms of music, the lower frequency means "lower pitch".
    • The processor i5 2450M is available in versions clocked with frequencies from 2.5 to 3,1 GHz,
    • the plates in most contemporary hard drives make 5400 revolutions per minute (5400 RPM),
    • long play vinyl record (LP) should be played at 33 1/2 revolutions per minut (RPM),
    • program 1 of Polish Radio can be listened in Poland and in neighboring countries on longwave (LW) at frequency 225 kHz,
    • wifi networks use electromagnetic waves with 2,4 GHz or 5 GHz frequency,
    • CD-AUDIO format uses sample rating of 44,1 kHz,
    • the frequency of alternating current (AC) is 50 or 60 Hz depending on the region,
    • etc.

How to convert

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    Examples:
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
