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 國際度量衡委員會 将 秒 定义为： 銫 133原子 基态 的兩個超精細 能階 間 躍遷 對應輻射的9,192,631,770個週期的持續時間 [5]，因此銫133原子基態的兩個超精細能階間躍遷對應輻射的频率被定义为9,192,631,770赫兹。 较高的频率可以使用kHz（10 3 Hz）、MHz（10 6 Hz） …

赫兹，是国际单位制中频率的单位，它是每秒钟的周期性变动重复次数的计量。赫兹简称赫。每秒钟振动（或振荡、波动）一次为1赫兹，或可写成次/秒，周/秒。因德国科学家赫兹而命名。

The hertz (symbol: Hz, definition: 1/s) is a unit derived from time which measures frequency in the International System of Units (SI). Frequency is how often something happens. A frequency of 1 hertz means that something happens once a second.

hertz, unit of frequency. The number of hertz (abbreviated Hz) equals the number of cycles per second. The frequency of any phenomenon with regular periodic variations can be expressed in hertz, but the term is used most frequently in connection with alternating electric currents, electromagnetic waves (light, radar, etc.), and sound.

It is defined as one event or cycle per second and represented as s⁻¹ in SI base units. One hertz equals one occurrence per second. We use this unit for periodic events. It is named after Heinrich Rudolf Hertz (1857–1894), who first demonstrated the existence of electromagnetic waves.

The hertz is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second (s). One hertz is the reciprocal of one second (1/s). The hertz is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves.

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。

2020年12月15日 · In any wave motion, you can define three quantities: velocity wavelength and frequency. Hertz is the SI unit for frequency. The unit is named after Heinrich Hertz, a prominent 18th century physicist. You can convert angular momentum in radians per second to hertz by using a conversion factor.
