Professionals, Teachers, Students and Kids Trivia Quizzes to test your knowledge on the subject. $\begingroup$ @eromod The conversion factor is only exact if you use that exact conversion factor. For example, an inch is defined as 2.54 cm. If you use that number, it has infinite precision. However, if you say "ahh, 2.5 is close enough" then the conversion factor only has 2 significant digits. Likewise here.
