It helps by your own measurements measure things but also understand how others see things and measure them...
Sometime languages are just enough to convey, though we can get better at it...
Assuming basic language and counting is enough without do the human homework is root to many problems, like consent, permission, understanding, sympathising etc..
Not expecting it all in one moment always helps making space and time for these things (not just work work work or cold counting).
It helps by your own measurements measure things but also understand how others see things and measure them... e.g 100 litres can see a lot for one person while very little for others.
Regardless of wrong or right, 1 or 0 people have their own gauge and reality which I guess we are trying to balance and harmonise*
(harmonise is slightly different as it considers the nature of the person and then also with others balancing it to work well / have a nice flow / tempo / speed / pleasant co-existence)
