In the example below, the quantity with the fewest number of sig figs is 27.2 (three sig figs). Your final answer is therefore limited to three sig figs. (27.2 x 15.63) ÷ 1.846 = 230.3011918 (this is what you calculator spits out) In this case, since your final answer it limited to three sig figs, the answer is 230. (rounded down)

Rules for Reporting Significant Figures. 1. Nonzero digits always count as significant figures. 2. Zeros are what mix people up. There are three situations in which they can occur. leading zeros precede all nonzero digits and are never significant (i.e., 0.000182 has three sign. figs.) captive zeros are between nonzero digits and are always ...

To minimize rounding errors, you may use more significant figures during intermediate calculations and adjust the significant figures only for the final results. Examples: 3.5 * 22.3 = 78 not 78.05, 6.2 / 833 = 0.0074 not 0.007442977 Adding or subtracting: 42.4 - 41.62 = 0.8, 4256 - 24.7 = 4231, 33.8 + 15.63 = 49.4.

We would record the mass as 42.5 ± g ,0. which means we are fairly confident that the actual 1 mass is between 42.4 g and 42.6 g. The uncertainty in our recorded mass would be ± 0.1 g. If we measured the mass of the same object with an analytical balance we might obtain a value of 42.467 g ± 0.001, which implies a mass between 42.46g and 42. ...

Rule For Stating Uncertainties - Experimental uncertainties should be stated to 1-significant figure. Ex. v = 31.25 ± 0.034953 m/s. vv = 31.25 ± 0.03 m/s (correct) The uncertainty is just an estimate and thus it cannot be more precise (more significant figures) than the best estimate of the measured value.

The rule for natural logs (ln) is similar, but not quite as clear-cut. For simplicity, we will use the above rules for natural logs too. 1 Using natural logs: ln 0.0056 = -5.1850 ln 0.0057 = -5.1673 ln 0.0058 = -5.1499. Note that the numbers each had two significant figures, and the results started to differ in the second decimal place.
