What does 'fold' mean

  1. Mar 12, 2005 #1
    When Someone says, "It increased by 10 fold", what does that mean?
    10 times the original amount, or amount^10 or something like that?

    It's an old expression, but it just means "times." Something increasing ten-fold means it's ten times what it used to be.

    Also occurs in "manifold", just FYI. :smile:
