Significant and decimal places for engineering report

Click For Summary

Discussion Overview

The discussion revolves around the appropriate use of significant figures and decimal places in engineering reports, particularly in the context of structural calculations involving dimensions, stresses, safety factors, and constants. The focus is on determining how many significant figures or decimal places are necessary for accurate and meaningful reporting.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant suggests that the answer to the question of significant figures is context-dependent, indicating that no two reports will have the same requirements.
  • Another participant emphasizes the importance of discerning the required significant figures based on the uncertainty of the values involved.
  • A third participant references a specific post for further clarification on the topic.
  • It is noted that reporting enough digits should be done to ensure the values are "meaningful."

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific number of significant figures or decimal places, indicating that multiple competing views remain regarding the appropriate approach.

Contextual Notes

The discussion highlights the dependence on the uncertainty of values and the subjective nature of what constitutes "meaningful" reporting, which may vary across different engineering contexts.

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"
