The 23 pages that link to Significant figures, each with the reason it gives.

• Measurement uncertaintyRelated: Rounding must not imply more precision than the uncertainty supports.

• Measurement errorRelated: Reporting precision limits how finely a measurement error can be expressed.

• Gravimetric analysisRelated: Reported analyte amounts cannot claim greater precision than the measured mass supports.

• Conversion of unitsRelated: A conversion changes units, not the precision supported by the measurement.

• Numerical stabilityRelated: Stability determines whether useful digits survive a sequence of computations.

• MeasurementRelated: Reported digits should reflect the resolution and uncertainty of the measurement.

• Scientific notationRelated: The coefficient can preserve how precisely a measured quantity is reported.

• Place valueRelated: Place value determines the magnitude represented by the last reported significant digit.

• Error propagationRelated: Reported digits should reflect the uncertainty obtained after propagation.

• Physical quantityRelated: Reported quantity values should not imply more precision than measurements support.

• Accuracy and precisionCompared with: Reported digits describe rounding and precision, not closeness to the true value.

• Order of magnitudeRelated: A magnitude estimate is rougher than the precision implied by many reported digits.

• RoundingRelated: Rounding to significant figures preserves a chosen number of informative digits.

• Slide ruleRelated: Scale spacing limits how many digits a slide rule can reliably show.

• Precision measurementCompared with: Digit-count conventions cannot replace a quantified uncertainty statement.

• Fixed-point arithmeticRelated: The fixed number of stored bits constrains precision across a format's range.

• Graduated cylinderRelated: The scale’s smallest divisions constrain how many digits a reported volume should contain.

• Benford's lawRelated: The first significant digit, rather than a number's written place value, determines the law's prediction.

• Vernier scaleRelated: Vernier readings add digits only when the instrument supports that resolution.

• Numerical digitRelated: A digit’s role can signal measurement precision, not only numerical value.

• Approximate measureRelated: Displayed digits can make an approximation appear more precise than its evidence supports.

• Parts-per notationRelated: The compact notation still requires precision to be communicated through appropriate significant figures.

• Surveyor's wheelRelated: The display's resolution does not guarantee equal accuracy in real terrain.
