**Orders of magnitude (time)**
Powers of 10³ seconds	equal to...	common units	orders of magnitude
10^-24 s	1 yoctosecond	--	1 ys, 10 ys, 100 ys
10^-21 s	1 zeptosecond	--	1 zs, 10 zs, 100 zs
10^-18 s	1 attosecond	--	1 as, 10 as, 100 as
10^-15 s	1 femtosecond	--	1 fs, 10 fs, 100 fs
10^-12 s	1 picosecond	--	1 ps, 10 ps, 100 ps
10^-9 s	1 nanosecond	--	1 ns, 10 ns, 100 ns
10^-6 s	1 microsecond	--	1 �s, 10 �s, 100 �s
10^-3 s	1 millisecond	--	1 ms, 10 ms, 100 ms
1 s	1 second	minute = 60 s	1 s, 10 s, 100 s
10³s (1000 seconds)	1 kilosecond (16.7 minutes)	hour = 3600 s day = 86 400 s = 86.4 ks week = 604.8 ks	10³ s , 10⁴ s , 10⁵ s
10⁶ s (1 million seconds)	1 megasecond (11.6 days)	month = 2.6 x 10⁶ s year = 31.6 Ms ~= π x 10⁷ s	10⁶ s , 10⁷ s , 10⁸ s
10⁹ s (1000 million seconds)	1 gigasecond (32 years)	century = 3.16 Gs ~= π x 10⁹ s millennium = 31.6 Gs ~= π x 10¹⁰ s	10⁹ s , 10¹⁰ s , 10¹¹ s
10¹² s	1 terasecond (32 000 years)	---	10¹² s , 10¹³ s , 10¹⁴ s
10¹⁵ s	1 petasecond (32 million years)	--	10¹⁵ s , 10¹⁶ s , 10¹⁷ s
10¹⁸ s	1 exasecond (32 billion years)	--	10¹⁸ s , 10¹⁹ s and more

The pages linked in the right-hand column contain lists of times that are of the same order of magnitude (power of ten). Rows in the table represent increasing powers of a thousand (3 orders of magnitude)

Note: Planck time, the shortest physically meaningful instant of time, is approximately 5.4 x 10^-44 s.
