    Measurement, Errors, Data and Unit Conversion
    A breath analyser unit to measure % blood alcohol content is accurate to ±0.005%. Which of the following displayed values will ensure that the reading is indeed greater than the legal driving limit of 0.05%?
    An accuracy of ±0.005% means that for a displayed reading of 0.055%, the actual value may be as low as 0.055–0.005 = 0.05% or as high as 0.055 + 0.005 = 0.06%, hence will be between 0.05% and 0.06%. To ensure that the actual % blood alcohol concentration is in fact above 0.05%, the reading should be more than 0.005 above the limit of 0.05%.
