Webb13 mars 2024 · Watch the reading if your thermometer is digital. If the reading fluctuates, the uncertainty is equal to the range of the fluctuation. For example, imagine that the … Webbpercentage uncertainty in the length by 2. Percentage uncertainty in A = 2 × 0.6% = 1.2% Therefore the uncertainty in A = 7100 × 1.2% = 85 mm2 So A = 7100 mm2 ± 1.2% or A = 7100 mm2 ± 85 mm2 b. Multiplying or dividing measurements The total percentage uncertainty is calculated by adding together the percentage uncertainties for each ...
