Convertir hora a segundo
Proporcione los valores a continuación para convertir hora [h] a segundo [s], o viceversa .
Hora
Definición: Una hora (símbolo: h) es una unidad de tiempo convencionalmente definida como 1/24 de un día y 3.600 segundos. En el tiempo universal coordinado, se puede incorporar un segundo bisiesto negativo o positivo para mantener la hora dentro de los 0,9 segundos del tiempo universal, lo que hace que una hora sea de 3599 o 3601 segundos en algunos casos.
Historia/origen: El término "hora" se deriva del anglo-normando "houre", que estaba en uso alrededor del siglo XIII .
Ha habido muchas definiciones de la hora a lo largo de la historia basadas en la cultura o la región, como la hora que se divide en 1/12 de un período de luz u oscuridad. Se cree que la costumbre de dividir el ciclo del día y la noche en 24 períodos comenzó con los antiguos egipcios.
Uso actual: La hora se utiliza globalmente como unidad de tiempo. La mayoría de las formas de empleo requieren un cierto número de horas trabajadas por día, y la compensación se basa en las horas trabajadas medidas o esperadas. Las duraciones a partir de 30 minutos (media hora) se usan comúnmente coloquialmente.
Segundo
Definition: A second is the base unit of time in the International System of Units (SI). It is defined based on cesium frequency, ΔνC, "by taking the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom to be 9,192,632,770 when expressed in hertz, which is equal to s-1." This definition was adopted in late 2018, and is largely the same as the previous definition, except that the conditions are more rigorously defined.
History/origin: Unlike many units that have had numerous definitions throughout history, the second has only had four different definitions.
The second was historically defined as 1/86400 of a day in 1832, which was based on the definition of a day as the approximate amount of time required for the Earth to complete a full rotation cycle relative to the sun.
The second was also defined as a fraction of an extrapolated year in the late 1940s with the advent of quartz crystal oscillator clocks. This resulted in a second defined as "1/31,556,925.9747 of the tropical year for 1900 January 0 at 12 hours ephemeris time," in 1956. This definition was adopted as part of SI in 1960.
In 1967, the second was defined exactly as "9,192,631,770 times the period of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom." This definition has since been updated as of late 2018 to be more rigorously defined, but otherwise, is effectively the same. This new rigor does not affect how the second is used in everyday life.
Current use: As the SI base unit of time, the second and its multiples are ubiquitous. There are few, if any, modern applications in which time is measured in a form other than the second and its multiples.

How to Convert Hour to Second
1 h = 3600 s
1 s = 0,0002777778 h
Ejemplo: convertir 15 h a s:
15 h = 15 × 3600 s = 54000 s
