The definition of steam pressure refers to the pressure exerted by steam in a vessel, which is a critical parameter in the operation of boilers and steam systems. This pressure is typically measured in pounds per square inch (psi) and directly reflects how much force the steam is pushing against the walls of the container (such as a boiler). Steam pressure is essential for determining the efficiency of steam systems, the performance of steam-driven equipment, and ensuring safety in operations, as it affects boiling point elevations, energy transfer, and the overall efficiency of thermal systems.

The other options describe related concepts but do not accurately represent the definition of steam pressure. For instance, the weight of steam produced in the boiler pertains more to the mass and volumetric flow of steam rather than the exerted pressure. Meanwhile, the amount of energy contained in a steam system describes the thermal energy available but does not specify pressure. The temperature of steam created within the boiler is also relevant since pressure and temperature are closely linked in steam systems, yet it does not encompass the definition of steam pressure itself.
