Abstract The problems on determining the significant figures of the measurement result and its uncertainty has been deeply investigated through the analysis of detailed data,based on the national standard of measuring technique and practical application.The significant digits of uncertainty of measurement should be taken two digits for unification in order to ensure the rounding off value closest to orginal value and easy to operate with standardized and unified rounding off method.
