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
