Key Stage 4

Meaning

Significant Figures are the number of digits representing the accurate value of a number.

About Significant Figures

Significant Figures begin with the digit representing the largest number.

A number may be correct to a given number of significant figures.

The number of significant figures is related to how resolution of a measuring instrument.

When performing a calculation the answer should never be given to more significant figures than the numbers used in the calculation.

Examples

π = 3.14159265359 correct to 12 significant figures.

π = 3.142 correct to 4 significant figures.

The diameter of Earth = 12,742,000m correct to 5 significant figures.

The diameter of Earth = 12,700,000m correct to 3 significant figures.

The diameter of Earth = 10,000,000m correct to 1 significant figures.
