Tolerance is a critical concept in livestock or trucking scales, as it determines the acceptable level of accuracy for weight measurements. Every scale has a weight capacity, and the percentage by which it can be off is determined by industry regulations and standards. This tolerance is important to ensure that buyers and sellers of livestock are getting accurate and reliable weight measurements, which ultimately affects the fair market value of the animals. For example, a vehicle scales with a weight capacity of 5,000 pounds may have a tolerance of +/- 0.5%, meaning it can only be off by a maximum of 25 pounds.
