SIGNIFICANT DIGITS IN MEASUREMENT

Significant figures - Wikipedia
OverviewIdentifying significant figuresArithmeticEstimating tenthsEstimationThe significant figures of a number are digits that carry meaning contributing to its measurement resolution. This includes all digits except: All leading zeros. For example, "013" has 2 significant figures: 1 and 3; Trailing zeros when they are merely placeholders to indicate the scale of the number; and Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment suppSee more on enpedia · Text under CC-BY-SA license
Determining Significant Figures - ThoughtCo
All zeros between other significant digits are significant. The number of significant figures is determined by starting with the leftmost non-zero digit. The leftmost non-zero digit is sometimes called the most significant digit or the most significant figure. For example, in the number 005, the '4' is the most significant figure.

When multiplying or dividing measurements, the answer should contain the same number of significant digits as the measurement with the least number of significant digits. In the example above, one of the measurements contained 2 significant digits, and the other measurement contained 3 significant digits.

Significant Digits and Measurement - The Biology Corner
Significant Digits and Measurement. Question: What digits are significant when recording a measurement? When scientists use an instrument, such as a ruler or graduated cylinder, the scientist can only measure as accurately as the instrument will allow.
Significant Digits - Chemistry LibreTexts
Introduction. Significant Digits - Number of digits in a figure that express the precision of a measurement instead of its magnitude. The easiest method to determine significant digits is done by first determining whether or not a number has a decimal point.
