What is 1.005 to two sig figs?
To take a number to two significant figures, you first take the greatest non-zero digit, and the one after it. In this case we'd have 1.0 Next you look at the third digit to see if the second digit should be rounded up, in this case the third digit is 0 so we don't round up. Thus the answer is 1.0, or written simply, 1

Determining Number of Significant Figures (Sig Figs)1.All non-zero numbers are significant. 6924 has four sig figs.2.Leading zeros are not significant. 0.0003679 has four sig figs.3.Zeros between other significant figures are significant. 0.00041092 has five sig figs.4.Trailing zeros are significant if there is a decimal. 0.046802000 has eight sig figs.Multiplication and DivisionRound the answer to the same number of significant figures (sig figs) as the measurement with the fewest sig figs in the problem.34.9cm x 4.7cm = 164.03cm2 = 160cm2 (rounded to two sig figs)271.0g/99.8cm3 = 2.71543g/cm3 = 2.715 (rounded to four sig figs)Addition and SubtractionRound the answer to the fewest decimal places as the measurement with the fewest decimal places.9.45kg + 8.329kg = 17.78kg (rounded to two decimal places)Rounding Rules:If the number to be dropped is less than four, keep the number in front the same. 3.43 would be rounded to 3.4 .If the number to be dropped is greater than five, round the number in front up by 1. 3.46 would be rounded to 3.5 .If the number to be dropped is exactly five, keep the number in front the same if it is even. If the number in front is odd, round up by 1.4.65 rounds to 4.6 .4.75 rounds to 4.8 .
