Why the dimension and edge length numbers does not tally when scaling objects? [duplicate]

I created a plane and set its dimensions to 32m x 4.5m. When using the edge length measurement tool, it shows 1m for every edge in the viewport.

Q: Why it doesn't display 32m x 4.5m in the viewport?

• This is due to the scale given in object mode. Apply scale Ctrl+A in object mode. – lemon Feb 23 '20 at 14:47
• @lemon, thank you. noted. I'm sorry but i don't understand the logic betwen the extra step...Kindly advice. Is there any way to automatically make the edge follow the dimension by default? – Ranvier Lee Feb 23 '20 at 14:51
• If you scale in edit mode it will work properly right away. – Robert Gützkow Feb 23 '20 at 15:08
• Does this answer your question? difference between dimension and scale in blender – thibsert Feb 23 '20 at 16:07
