###### Example 6.2.5

To get a sense of how scientific notation works, let's consider familiar lengths of time converted to seconds.

Length of Time | Length in Seconds | Scientific Notation |

one second | 1 second | \(1 \times 10^{0}\) second |

one minute | 60 seconds | \(6 \times 10^{1}\) seconds |

one hour | 3600 seconds | \(3.6 \times 10^{3}\) seconds |

one month | 2,628,000 seconds | \(2.628 \times 10^{6}\) seconds |

ten years | 315,400,000 seconds | \(3.154 \times 10^{8}\) seconds |

79 years (about a lifetime) | 2,491,000,000 seconds | \(2.491 \times 10^{9}\) seconds |
