order of magnitude vs ratio

order of magnitude

noun
  • The class of scale or magnitude of any amount, where each class contains values of a fixed ratio (most often 10) to the class preceding it. For example, something that is 2 orders of magnitude larger is 100 times larger, something that is 3 orders of magnitude larger is 1000 times larger, and something that is 6 orders of magnitude larger is a million times larger, because 10² = 100, 10³ = 1000, and 10⁶ = a million. 

ratio

noun
  • The relative magnitudes of two quantities (usually expressed as a quotient). 

  • A number representing a comparison between two named things. 

  • The number of comments to a post or other expression on social media relative to the number of likes; a high ratio suggests disagreement with the contents of the original post. 

verb
  • To respond to a post or message on social media in a greater number than the number of likes the post receives, especially to condemn or mock the original poster. 

intj
  • Indicates disagreement with a post the user disagrees with or dislikes.
