Often used in formal or serious contexts.. On the other hand, 承知する (しょうちする (shouchi suru)) maps to "to understand; to accept; to be aware of" (Syllabus Level: N3) and represents A formal way to say 'to understand' or 'to acknowledge'. Often used in business or polite contexts when accepting a request or acknowledging information. Less casual than わかる.
