Two-figure accuracy refers to a measurement of precision where a value is expressed with two digits after the decimal point. For example, an accuracy of 99.99% would be considered two-figure accurate, indicating that the value is reliable to the hundredth place. This level of accuracy is often important in fields like finance, engineering, and scientific research, where small differences can have significant implications.

Circumference = 2*π*r = 12.566 feet (to 3 dp - five significant figures)To the same accuracy as the one significant figure in the question: 10 feet
As per ANSI 12.2 does this simply mean a +/- 2% accuracy ?

It depends to what degree of accuracy: 10.25 (2 Decimal Places) 10.3 (1 Decimal Place) 10 (0 Decimal Places) 10 (1 Significant Figure) I included 1 Significant Figure for your future reference. If the number was 11.245 then to 1 Significant figure would be 10 because 0 does not count as a figure and therefore the 1 in 11 would be the only FIGURE.

One figure accuracy is when it is rounded to the nearest 10, 100, 100.
Sonar, RADAR and satellites and space travel improved the accuracy of maps after World War 2.
