The second is an important unit of time. It is the main unit of time in the SI system of units. It can be defined as the time it takes an electromagnetic field to propagate through 3 x 10 ⁵ km of vacuum.

One solar day has 86,400 seconds. There are 60 second per minute.

Second is not small and specific enough to be used by scientists and engineers so smaller units were derived such as:

• One millisecond which equals 10 ^-3 s.
• One microsecond which equals 10 ^-6 s.
• One nanosecond which equals 10 ^-9 s.
• One picosecond which equals 10 ^-12 s.
