Time has the SI unit second.
Scientists have measured the world’s smallest unit of time, and it’s called the zeptosecond. It was recorded by a group of scientists at Goethe University in Germany and published in the Science journal. One second is the time interval between the two consecutive ticks you hear from the pendulum wall clock.
1 min = 60 s
1 h = 60 min. = 3600 s.
1 day = 24 h = 86400 s.
1 year = 365 days = 3.15 × 107 s.
