1 E10 s - Definition and Overview

To help compare orders of magnitude of different times this page lists times between 10¹⁰ seconds and 10¹¹ seconds (320 years and 3200 years). See also times of other orders of magnitude.

• Shorter times
• 351 years -- half-life of californium-249
• 418 years -- half life of silver-108
• 432.2 years -- half life of americium-241
• 680 years -- half life of niobium-91
• 898 years -- half life of californium-251
• 1000 years -- one millennium = 3.16 x 10¹⁰ seconds
• Longer times

In this and shorter time intervals the "time since" entries should be replaced by reference to the articles for each century, decade, and year; e.g. 17th century, 1670s, 1671.
