Stories and Lessons Learned

Story 1: A construction worker needs to cut a piece of wood that is 18cm long. However, the saw he is using is calibrated in inches. The worker mistakenly assumes that 18cm is equal to 8 inches and cuts the wood too short.

Lesson learned: Always double-check your measurements and ensure that you are using the correct conversion factor.
