In what units is Standard Post weighed?

Standard Post is weighed in pounds, along with consideration of the zone where it is addressed. This means that the shipping cost is influenced not only by the weight of the package but also by the distance it needs to travel based on postal zones. The U.S. Postal Service uses zones that are determined by the distance to the destination from the point of origin.

When calculating shipping costs for Standard Post, the combination of weight (in pounds) and the zone allows for accurate pricing. It's important for postal employees and customers to understand this system, as it affects how packages are processed and shipped.

The other options do not fully capture the components involved in the weight measurement for Standard Post. For example, weighing only in kilograms ignores the standard measurement used in the U.S., while measuring only by volume would not account for actual weight, which is crucial for determining postage. Similarly, stating dimensions without weight does not align with how postal rates are calculated. Thus, the correct option reflects the comprehensive approach the postal system uses for pricing based on both weight and delivery zone.
