Are shipping scales estimated or exact?

For shipping scales, it is true that estimates are generally used and that there can be a lack of strict requirements for the calibration of scales. Shipping scales, often used in shipping and logistics contexts, may not always provide the level of precision that exact weights require, especially in less formal settings. In many cases, the accuracy of the scale depends on how well it has been calibrated and maintained, which can vary.

The use of estimates allows for more flexibility and can simplify processes in shipping operations, especially when precise weight measurements are not critical for the service being rendered.

While scales should ideally be calibrated for accuracy, in practice, this is not always enforced, leading to the possibility that customers may receive weight estimates rather than exact measurements. This helps streamline the shipping process but also means that the weights provided may not always reflect precise values. The other options suggest absolutes that do not account for the variability and common practices in shipping scale use.
