What this part means
The expressions on both sides represent the same quantity under the stated assumptions.
Its job in the formula
The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula
Heat removal is fundamentally a problem of area, not of power alone. The quantity engineers actually design against is heat flux, power divided by the surface area it must leave through: . with q'' expressed in watts per square centimetre. Doubling a chip’s power without changing its package size doubles q'' , and every downstream cooling decision in this article follows from trying to hold q'' within what a given cooling medium can actually carry away from that specific surface before the silicon beneath it exceeds its rated temperature.
