Basic Time Units:

Second (s): 
The base unit of time in the International System of Units (SI). It is defined as the duration of 9,192,631,770 periods of radiation from the cesium-133 atom.
One second = 1 s. 
Minute (min): 
A unit of time equal to 60 seconds.
One minute = 60 seconds.
Hour (hr): 
A unit of time equal to 60 minutes or 3,600 seconds.
One hour = 3,600 seconds.
Day (d): 
A unit of time equal to 24 hours or 86,400 seconds.
One day = 86,400 seconds.
Week (wk): 
A unit of time equal to 7 days.
One week = 604,800 seconds.
Month (mo): 
The average month length is approximately 30.44 days (based on the Gregorian calendar).
One month ≤ 2,628,000 seconds.
Year (yr): 
A unit of time-based on Earth's orbit around the Sun. The Gregorian calendar defines one year as 365 days or 366 days in a leap year.
One year = 31,536,000 seconds.
Decade (dc.): 
10 years.
One decade = 315,360,000 seconds.
Century (c.): 
100 years.
One century = 3,153,600,000 seconds.

Smaller Time Units:

Millisecond (ms): 
A unit of time equal to one-thousandth of a second.
One millisecond = 0.001 seconds.
Microsecond (�s): 
A unit of time equal to one-millionth of a second.
One microsecond = 0.000001 seconds.
Nanosecond (ns): 
A unit of time equal to one-billionth of a second.
One nanosecond = 0.000000001 seconds.
Picosecond (ps): 
Equal to one-trillionth of a second.
One picosecond = 0.000000000001 seconds.
Femtosecond (fs): 
Equal to one quadrillionth of a second.
One femtosecond = 0.000000000000001 seconds.
Attosecond (as): 
Equal to one-quintillionth of a second.
One attosecond = 0.000000000000000001 seconds.
Yoctosecond (ys): 
The smallest measurable unit of time, equal to one-septillionth of a second.
One yoctosecond = 0.000000000000000000000001 seconds.

Traditional and Historical Time Units:

Fortnight (fn): 
A unit of time equal to 14 days. 
One fortnight = 1,209,600 seconds.
Lustrum (lu): 
A historical Roman unit of time representing 5 years.
One lustrum = 157,680,000 seconds.

This Basic Time Conversion Calculator covers many time units, from standard units like seconds and hours to smaller scientific units like nanoseconds and yoctoseconds and traditional units like fortnights and lustrums. It is a versatile tool for converting between different scales of time across everyday, scientific, and historical contexts.
