1 second

To help compare orders of magnitude of different times this page lists times between 10⁰ seconds and 10¹ seconds (1 second and 10 seconds). See also times of other orders of magnitude.

• shorter times
• 1 second – the second is the metric standard unit for time; approximately the same as a human cardiac cycle
• 1 second; the amount of time it takes light in a vacuum to travel 299792458 metres or approximately 300,000 km (~186,282 miles)
• 1.2096 seconds – a VMS microfortnight
• 1.26 seconds – approximate time it takes light to travel between Earth and the Moon
• 3.16 seconds– one thousand-millionth (10^-9) of a century. Its closeness to π in value leads to the expression "Pi seconds is a nanocentury".
• 9.77 seconds – world record for the men's 100 m sprint event (Asafa Powell, 2005 and Justin Gatlin, 2006)
• longer times
