Hertz - Wikipedia
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]

Hertz - Simple English Wikipedia, the free encyclopedia
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.
SI Units – Time | NIST
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.

The hertz is the unit of frequency in the International System of Units (SI) and its symbol is Hz. 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.
Hertz (Einheit) – Wikipedia
Das Hertz (Einheitenzeichen: Hz) ist die SI-Einheit der Frequenz. Sie gibt die Anzahl sich wiederholender Vorgänge pro Sekunde in einem periodischen Signal an. Die Einheit wurde 1930 nach dem deutschen Physiker Heinrich Hertz benannt.
赫兹 (Hz) 单位定义 | Math Converse
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.
What is a hertz (HZ)? | Definition from TechTarget
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).
