How to memorize distances

Hi I know the Memory Palace can be applied to a lot of stuff, be it Cards, Maths, Chemistry, Poetry, Books, even Dance Steps! I wanted to ask if it cluld be applied to remember distances, such as the distance between the comma in 350,0 mg and 0,3500 g the distance would be 0,350,0 you may not need it but there are lots of distances by eye that would be quite useful.
Is it possible to remember distances and how?
Idk how to search about it so forgive me if theres another thread.
Thank you

Do you only want to remember the distance in characters (like “3 characters”), or something to do with math? (like division by 1,000)

Would remembering the number 3 be enough? (Example: number shapes)
