Om denne kalkulatoren
A frequency converter changes a rate of repetition between hertz, kilohertz, megahertz and gigahertz, plus revolutions per minute and radians per second. Values convert through the hertz — one cycle per second — as a common base.
The SI steps are simple powers of a thousand: 1 kHz = 1,000 Hz, 1 MHz = 1,000,000 Hz and 1 GHz = 1,000,000,000 Hz. The two odd ones out are RPM, which is cycles per minute (divide by 60 to reach hertz), and radians per second, which is 2π times the frequency in hertz.
Worked example: to convert 3,000 RPM to hertz, divide by 60, giving 50 Hz. To express a 2.4 GHz Wi-Fi signal in hertz, that is 2,400,000,000 cycles per second. A results table shows the same frequency in every unit at once, useful for radio, audio and rotating machinery.
Ofte stilte spørsmål
Hvor mange Hz er det i en MHz?
One megahertz is 1,000,000 hertz, and one gigahertz is 1,000 megahertz. A 2.4 GHz Wi-Fi signal cycles 2.4 billion times per second.
Hvordan konverterer jeg RPM til Hz?
Divide RPM by 60, since hertz is cycles per second. A motor at 3,000 RPM turns at 50 Hz.
Hva er radianer per sekund?
Vinkelfrekvensen i rader er 2π ganger frekvensen i hertz. 1 Hz er omlag 6,2832 rader.
Hvor mange megahertzer er det i en gigahertz?
One gigahertz is 1,000 megahertz, or one billion hertz. A 3.2 GHz processor clock therefore ticks 3.2 billion times each second.
Hvordan konverterer jeg Hz til RPM i denne frekvensomformeren?
Denne frekvensomformeren multipliserer hertz med 60 for å nå omdreininger i minuttet, siden RPM teller med sykluser i minuttet. så 50 Hz tilsvarer 3000 RPM.
Hvordan konverterer jeg kHz til MHz?
One megahertz is 1,000 kilohertz, so divide kilohertz by 1,000 to get megahertz. A 1,500 kHz AM radio station broadcasts at 1.5 MHz.
