WebSignificant Figures (Sig. Figs.) The mass of an object weighed on a triple beam balance (precision ± 0.1g) is found to be 23.6 g. This quantity contains 3 significant figures, i.e., three experimentally meaningful digits. If the same measurement is made with an analytical balance (precision ± 0.0001g) , the mass might be 23.5820 g (6 sig. fig.) Web1.1 has two significant figures (1, 1). 13.55 has four significant figures (1, 3, 5, 5). Rule 2 - any zero contained between two non-zero numbers is significant If a zero forms part of a string of digits AND falls between two non-zero digits then it must be counted as a significant figure. Examples:

WebThe mantissa is .021 and has 3 digits because 10.5 has 3 sig figs). NOTE: It is the number of digits , not the number of sig figs in the mantissa 7. For exponents, the number of sig figs is the same as the number of digits in the mantissa. For example 101.23 = 17 or 1.7 x 101. This has 2 sig figs because there are 2 digits in the mantissa (.23). 8. Web13 jan. 2024 · I get at most 3 significant figures (I've seen 21.6 C) but the A/.D converter in the sensor works in bits of resolution. Natively it does degrees C but 21.6 is probably 216 counts.
