Convert watt/square metre to joule/second/square metre
Watt/Square Metre
The watt per square metre (W/m²) is the SI unit of heat flux density and irradiance. It represents the power transmitted per unit area. The solar constant (total solar irradiance) at Earth's orbit is approximately 1361 W/m². Used in heat transfer engineering, solar energy, and thermal radiation analysis.
Joule/Second/Square Metre
The joule per second per square metre (J/(s·m²)) is dimensionally equivalent to the watt per square metre (W/m²), since 1 J/s = 1 W. It is used when emphasising the energy-flow interpretation of heat flux rather than the power interpretation, especially in educational and scientific contexts.

How to convert Watt/Square Metre to Joule/Second/Square Metre
1 W/m² = 1 J/(s·m²). To convert any value, multiply it by 1. For example, 25 W/m² = 25 J/(s·m²).
