Step 3: Divide that answer by the accepted value. 2cm 17cm = 0.12 2 c m 17 c m = 0.12 (by rounding off to two significant figures) Step 4: Multiply that answer by 100 and add the % symbol to express the answer as a percentage. 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. bubs nutrition
