Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future.
Scientific Note: The second is the SI base unit of time, 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 cesium-133 atom.
Second (s): The SI base unit of time. Used worldwide in science, engineering, and everyday measurements.
Minute (min): Equal to 60 seconds. Commonly used for everyday time measurements.
Hour (hr): Equal to 60 minutes or 3,600 seconds. Standard unit for measuring longer periods.
Day (d): Equal to 24 hours. Based on Earth's rotation period.
Week (wk): Equal to 7 days. Widely used in calendars and scheduling.
| From | To | Formula |
|---|---|---|
| Seconds (s) | Minutes (min) | min = s / 60 |
| Minutes (min) | Seconds (s) | s = min × 60 |
| Hours (hr) | Minutes (min) | min = hr × 60 |
| Days (d) | Hours (hr) | hr = d × 24 |
| Weeks (wk) | Days (d) | d = wk × 7 |
| Months (mo) | Days (d) | d = mo × 30.437 (average) |
| Years (yr) | Days (d) | d = yr × 365.25 (average) |
| Seconds (s) | Milliseconds (ms) | ms = s × 1000 |
Accuracy Note: Month and year conversions use average values (30.437 days/month, 365.25 days/year). For precise calendar calculations, use specialized tools.
Time is measured in various units depending on the context, from extremely small units used in physics to large units used in astronomy.
