<P> For quantities created from measured quantities by multiplication and division, the calculated result should have as many significant figures as the measured number with the least number of significant figures . For example, </P> <Dl> <Dd> 1.234 × 2.0 = 2. 468...≈ 2.5, </Dd> </Dl> <Dd> 1.234 × 2.0 = 2. 468...≈ 2.5, </Dd> <P> with only two significant figures . The first factor has four significant figures and the second has two significant figures . The factor with the least number of significant figures is the second one with only two, so the final calculated result should also have a total of two significant figures . </P>
