WebThe quarter weighs about 6.72 grams, with a nominal uncertainty in the measurement of ± 0.01 gram. If we weigh the quarter on a more sensitive balance, we may find that its mass is 6.723 g. This means its mass lies between 6.722 and 6.724 grams, an uncertainty of 0.001 gram. Every measurement has some uncertainty, which depends on the device ... Webthe uncertainty associated with a single measurement. The following general rules of thumb are often used to determine the uncertainty in a single measurement when using a scale or digital measuring device. 1. Uncertainty in a Scale Measuring Device is equal to the smallest increment divided by 2. 2 smallest increment σx = 2.
