关于此计算器
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.
经常问到的问题
兆赫中有多少赫?
一种兆赫是1,000,000赫兹,一种千兆赫是1,000兆赫。2.4兆赫无线-无线信号周期为每秒24亿次。
我该如何将RPM转换成Hz?
将RPM除以60, 因为赫兹是每秒的周期。 3 000 RPM 的发动机在50赫兹旋转。
每秒的弧度是多少?
弧度/秒中的角频率等于赫兹中的频率的2-瓦。因此,1赫兹约为6.2832 rads/秒。
千兆赫里有多少兆赫?
千兆赫是1000兆赫,或10亿赫兹。因此,3.2千兆赫处理器时针每秒可勾选32亿次。
我如何将Hz转换成RPM 的频率转换器?
This frequency converter multiplies hertz by 60 to reach revolutions per minute, since RPM counts cycles per minute. So 50 Hz corresponds to 3,000 RPM.
我如何将 kHz 转换为 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.
