What does watt per square meter measure?

Watt per square meter measures heat flux density, indicating the rate of heat transfer per unit surface area in the metric system.

When should I use watt per square inch instead of watt per square meter?

Watt per square inch is used for heat flux measurements on small surfaces, especially in contexts like electronics cooling or laser heating.

Is the conversion between these units exact?

The conversion uses a defined rate based on area equivalence, but precision depends on the accuracy of metric-to-imperial area conversion.
