Does absolute uncertainty have units

WebThe uncertainty range for the measurements reaches from 9.6 m/s 2, to 9.9 m/s 2 while the absolute uncertainty is approximately equal to half of our range, which is equal to the difference between the maximum and minimum values divided by two. \[\frac{9.9 m/s^2 - 9.6 m/s^2}{2} = 0.15 m/s^2\] The absolute uncertainty is reported as: WebSo, two measurements with the same absolute uncertainty can have different percent uncertainties. The percent uncertainty is useful to see how significant the uncertainty is. In the example here, we had two measurements with the same absolute uncertainty of ± 0. 5 cm but different measured lengths of 5 cm and 50 cm.
