"Vă rog cântăriți aceste mere."

Translation: Please, weigh these apples.

[splittongue]

Shouldn't "scale" be accepted too?

[BenYoung84]

In place of "weigh"? "scale" is possible in that context but is very unusual. People will think you are an ant climbing over the apples.

[cosmo-pedant]

The English noun "scale" = "scara" in Romanian. Can "scara" be a verb? (Please forgive my lack of diacritics.)

[Shaji274654]

why we cannot say "Please, you weigh these apples"

[Renardo_11]

"Vă rog" strongly suggests that the following "cântăriți" is an imperative. Context matters.
