Usage Notes

精确 is close in meaning to 准确 (zhǔnquè, accurate/correct), but 精确 emphasizes fine-grained numerical or technical precision, while 准确 is more general. In scientific and technical writing, 精确 is the preferred term. Its antonym is 粗略 (cūlüè, rough/approximate).

Memory Hook

精 means "refined/essence" and 确 means "certain/sure" — 精确 is being "refined to a certainty," with no room for approximation.
