Usage notes edit

  • Some writers and speakers use constructions like "an increase by twofold" to mean "a twofold increase". This can lead to confusion, as the logical rendering of "an increase by twofold" would imply "a 200% increase of the original amount" and the latter "an increase to 200% of the original amount". Caution should be taken to avoid such confusion. Typically, -fold takes no preposition.
  • In scientific contexts, "-fold" is sometimes appended to numerals (with the same sense), as in a 2010 paper by M.C. Stone et al., which mentions "10-fold up-regulation of the number of growing microtubules" in its abstract.
