Significant and decimal places for engineering report

[n707jt]

Hi

I was wondering when I am completing a structural calculation engineering report with values like dimensions, stresses, safety factor and constants etc, to what significant number or decimal place should I put them?

The best answer is "it depends," no two reports will have the same requirement. An engineer needs to be able to discern required sig figs for a calculation and result.

in what we do, it depends upon the uncertainty of the values,
then reporting enough digits to be "meaningful"
