The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. [1] [a] The hertz is an SI derived unit whose formal expression in terms of SI base units is s −1, meaning that one hertz is one per second or the reciprocal of one second. [2]

赫兹（hertz ），也称为赫兹（ hertz ），是国际单位制（SI）频率单位。换句话说，赫兹是表示物理现象在一秒钟内重复次数的单位。 更准确地说，1 赫兹等于 1/s。因此，一赫兹的频率意味着所研究的物理现象每秒仅重复一次。

2025年3月19日 · 赫兹是以首个用实验验证 电磁波 存在的科学家 海因里希·赫兹 命名，常用于描述 正弦波 、 乐音 、 无线电 通讯以及计算机 时钟频率 等。 赫兹的定义为每一秒周期性事件发生的次数 [4]，而 国际度量衡委员会 将 秒 定义为： 铯 133原子 基态 的两个超精细 能级 间 跃迁 对应辐射的9,192,631,770个周期的持续时间 [5]，因此铯133原子基态的两个超精细能级间跃迁对应辐射的频率被定义为9,192,631,770赫兹。 较高的频率可以使用kHz（10 3 Hz）、MHz（10 6 Hz） …

2010年4月12日 · The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second. Standard frequencies and the correct time are broadcast by radio stations WWV and WWVB in Colorado, and WWVH in Hawaii.

Hertz (Hz) is the standard unit of frequency in the International System of Units (SI). It is a derived unit based on the second (s), one of the seven base units in the SI standard. The base units, in turn, are constructed from the seven SI defining constants. The SI equation for hertz is Hz = s -1 (also written as Hz = 1/s).

2024年7月3日 · Hertz, the unit of frequency, measures cycles per second. Widely used in telecommunications, electronics, and physics, its SI multiples help express frequencies across scales. From radio waves to computer processors, Hertz plays a crucial role in technology and scientific research.

The hertz, symbol Hz, is the SI coherent derived unit of frequency. It is the special name for the reciprocal second, symbol s -1 . One hertz is defined as one cycle per second.

The hertz (symbol: Hz) is the SI unit of frequency. It is named in honor of the German physicist Heinrich Rudolf Hertz, who made important scientific contributions to electromagnetism.

2018年5月29日 · hertz (symbol: Hz) The SI unit of frequency. A periodic phenomenon has a frequency of one hertz if each cycle of the phenomenon repeats itself in a period of one second. A megahertz (MHz) is one million (10 6) hertz; a gigahertz (GHz) is 1000 million (10 9) hertz.
