In a paint curing measurement system and method, the number of products input to an paint curing production line, the frequency of spraying primer on the surfaces of the products, the frequency of drying the primer on the surfaces of the products, a frequency of spraying topcoat on the surfaces of the products, and a yield of the products are calculated. Accordingly, production performance of the paint curing production line is determined. The production performance is output to an output device.
