Terasecond and longer

From Simple English Wikipedia, the free encyclopedia

A terasecond (symbol: Ts) is one trillion seconds. That is about 31,700 years. It can be written as 1012 seconds.

Here is a list of time spans longer than 1 terasecond:

  • 1015 seconds = 1 petasecond = 31.7 million years
  • 1018 seconds = 1 exasecond = 31.7 billion years
  • 1021 seconds = 1 zettasecond = 31.7 trillion years
  • 1024 seconds = 1 yottasecond = 31.7 quadrillion years
  • 1027 seconds = 1 ronnasecond = 31.7 quintillion years
  • 1030 seconds = 1 quettasecond = 31.7 sextillion years
