In our labs we often need to find the error percent between the expected value and the measured value. So if we expected to get a value of 9.8 m/s(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}for g but got 9.9 m/s^{2}instead, we say that the error was (9.9 - 9.8)/9.8 % = 1.02%. But what happens if we expect a value of 0 for something, and measure 1cm instead?
