sekondës

Sekondës, also known as seconds, are a unit of time in the International System of Units (SI). One second is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom. This definition was adopted in 1967 and has been used since then to standardize timekeeping.

In everyday life, seconds are commonly used to measure short durations, such as the time it takes for an event to occur or the duration of a task. They are also used in various fields, including science, engineering, and sports, to record and analyze time-sensitive data.

The second is a fundamental unit of time in the SI system, and it is related to other units of time, such as minutes and hours. One minute is equal to 60 seconds, and one hour is equal to 3,600 seconds. The second is also related to the day, which is approximately 86,400 seconds long.

In addition to the standard second, there are also other units of time that are used in specific contexts, such as the millisecond (1/1,000 of a second) and the microsecond (1/1,000,000 of a second). These units are used to measure very short durations, such as the time it takes for a signal to travel a certain distance or the duration of a chemical reaction.
