Necessity and feasibility of uncertainty calculations in fundamental chemistry experiments were discussed depending on the current situation of uncertainty application. It was recommended that main sources of error is identified according to the basis of learning error theory and calculated directly when true value was known, and the main components of uncertainty be determined when the true value was unknown. Uncertainty was calculated by considering 1~2 main components of uncertainty and ignoring minor components of uncertainty. The method for uncertainty calculation described above meets the requirements of fundamental chemistry experiment.
