How many pounds are in a short ton?

A short ton, commonly used in the United States, is defined as being equivalent to 2,000 pounds. This measurement is part of the customary system of units used in various industries, including construction, transportation, and shipping. Understanding the short ton is crucial for tasks such as calculating weight limits for vehicles or containers and ensuring compliance with safety regulations. The other options do not accurately reflect the standard conversion of a short ton to pounds, which is why they do not represent the correct answer.
