WebThe reading error for a standard ruler with mm increments is +/- 0.1mm under perfect conditions. That is, no parallax error and the ruler is close enough to the device being measured to guess at 1/10 increments of a mm. In your example, the smallest increments are 1 cm, so this ruler should easily give a measurements error of +/- 0.1cm. WebError is the difference between the actual value and the calculated value of any physical quantity. Basically, there are three types of errors in physics, random errors, blunders, and …

WebNov 14, 2024 · The margin of uncertainty in a single reading is taken to be half the smallest increment on the measuring scale. This is because any reading should be rounded to the increments given on the scale. For example, if you measure the length of a pencil as 15cm to the nearest cm, the true length could be anywhere between 14.5 and 15.5cm.
