Lab 2 - Measurement anlab you will becon far with metric system of measure "lowing relationships are useful Imeters (mm). The im = 1000 mm To convert from cm to m, divide by 160. Themeters'). For a box-shaped object, the volume (V) is given by the relation. "cubic Figure 1 r Equits volume is measured in lers: Her = 1000 ml grams (9) or kilograms the youth of matter an object has. It is usually meas Treasuring device. Each measuring device has a smallest unk that can be accurately mostwww youtube commoner carmelokeeponce in mass as small as 0.1 gram estimate to result 26 142 54. Maybe your we pamer wilpassing 12you might reading to the next of the same day always a guess and may vary even fran There is millimeter there are. If you measure that something is 23 s ked Bobs me rom exactly. Guess the last dat if it's a ladle less than 23. you more read " as 22 8 more like 22.9 mm. The last agt is always a guess. so it's normal for there to be possible factors that affect the resuk an experimenter may choose to take har the east count of the instrument as uncertainty or they may simply guess (provide the best de) about the uncerta eslute Deviations (AD) from me means jay taken as the average of the AD - 's - 21 + 1x, - 81 + w + Wxx - 81 alves is' measuresare 'scar estimate most common way to show the range of Precision 's how close repealed measure ments care to con t oiler f device that can he nearest meter. See diagram belay "cert diference , or percent minor Value. it is common to express the different %% error = lmeasured value - actual rafael x 100 solute value is used so the percent error is always poslive. In that case we talk of percent difference or discrepancy.
