User Guidelines

To achieve accurate results with the Stefan-Boltzmann Calculator, follow these guidelines:

• Temperature (K): Enter the absolute temperature in Kelvin. For example, room temperature is approximately 300 K. Ensure the value is positive.
• Surface Area (m²): Input the surface area of the object in square meters. The default is 1 m² for simplicity.
• Emissivity (0 to 1): Specify the emissivity, a value between 0 and 1. A perfect black body has an emissivity of 1 (default).
• Validation: Ensure all inputs are positive numbers, and emissivity is between 0 and 1. Invalid inputs will trigger an error message.
• Result Interpretation: The output is the total power radiated in watts, displayed with appropriate precision.
