The typical unit of measurement for working pressure in a boiler can indeed vary based on different standards and practices, which is why the most inclusive answer is that all of the units listed are valid. Bar is commonly used in many parts of the world, particularly in Europe, to express pressure. Pascal is the SI unit for pressure and is used in scientific contexts, although it may be less common on practical boiler applications. Pound per square inch (psi) is widely utilized, especially in North America, to indicate pressure in many industrial settings, including boiler operations.

Recognizing that each of these units can represent pressure effectively ensures that operators and engineers can communicate clearly across different regions and technical backgrounds. Utilizing multiple measurement units allows for flexibility in various applications and adherence to local regulations and standards. Thus, understanding that working pressure can be expressed in any of these ways underscores the importance of technician familiarity with these different units when dealing with boiler systems.
