Time Unit Knowledge
Basic Time Units
Time is a fundamental physical quantity that measures the duration of events. The basic time unit in the International System of Units (SI) is the second (s), with other common units including minutes (min), hours (h), days (d), weeks (wk), months (mo), and years (yr).
Definition of Second
The second is the modern base unit of time. According to the SI definition, 1 second equals the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.
Common Time Unit Conversions
- 1 minute = 60 seconds
- 1 hour = 60 minutes = 3,600 seconds
- 1 day = 24 hours = 1,440 minutes = 86,400 seconds
- 1 week = 7 days = 168 hours = 604,800 seconds
- 1 month (average) ≈ 30.44 days ≈ 2,629,746 seconds
- 1 year (Gregorian) = 365 days or 366 days (leap year) ≈ 31,536,000 seconds
- 1 century = 100 years.
Microscopic Time Units
- Millisecond (ms) = 1/1,000 second
- Microsecond (μs) = 1/1,000,000 second
- Nanosecond (ns) = 1/1,000,000,000 second
- Picosecond (ps) = 1/1,000,000,000,000 second. These units are widely used in computer science, physics, and electrical engineering.
Special Time Units
- A sidereal day is the time it takes Earth to rotate once relative to the stars rather than the Sun, approximately 23 hours 56 minutes 4 seconds
- A sidereal year is the time it takes Earth to orbit the Sun once, approximately 365.25636 days
- A tropical year is the interval between two successive vernal equinoxes, approximately 365.24219 days
- A shake is a unit of time used in nuclear physics, equal to 10 nanoseconds.
