Info about "Week"

In today’s culture, the “week” is a common unit of time comprising seven days. However, it is neither a legal unit nor a physical unit of time in terms of the International System of Units(SI), compared to seconds, minutes or hours.

Here, 1 week is equivalent to 7 days, 1 day is therefore equal to 0.14286 weeks.

Historically, the combination of seven days into a unit of one week can be traced back to the length of one moon. The entire phase from full moon to another full moon lasts slightly longer than 28 days. This is divided into four lunar phases (full moon - waning crescent - new moon - waxing crescent - full moon), which suggests the division of the 28 days into four weeks of seven days each.

Info about "Second"

The second (s) is the base unit of time in the International System of Units (SI). Therefore, the second is the physical unit of time measurement.

All other units of time are derived from the second (e.g., 1 minute = 60 seconds, 1 second = 1,000 milliseconds).

Until the middle of the 20th century, the second was defined as the sixtieth part of a minute of the day divided into 24 hours of 60 minutes. Since the rotation of the earth was assumed to be uniform, the length of a day and that of a second always appeared to be the same. It was not until 1934 that the long-held assumption that the Earth's rotation is not uniform was proven. As a result of magma displacements beneath the Earth's mantle and tidal friction, the Earth's rotation gradually slows down and thus the astronomical length of the day becomes longer. It turned out that the continuously improved quartz clocks provided a more consistent measure of time than the Earth's rotation. For this reason, a leap second is now added every 2 to 5 years to synchronise all clocks with the day, which always becomes a few fractions of a second longer.

Since 1967, the second has been defined as 9,192,631,770 times the period of a microwave, which resonates with a selected transition between two energy levels in the cesium atomic resonance. Therefore, it is called the atomic second Based on this definition. Atomic clocks are based on the exact measurement of this transition, and thus supersede quartz clocks in terms of accuracy.

Basis for conversion Week (weeks) to Second (s)
