What term describes the force required to deflect a spring by one inch?

The key idea is the force needed per unit of displacement for a spring. That is defined by the spring rate (also called the spring constant). It quantifies how much force is required to produce one unit of deflection. For a spring, F = k × Δx, so if you deflect it by one inch, the force you must apply equals the spring rate (often expressed in pounds per inch in Imperial units). This is why spring rate is the best description here. Stiffness is a related idea, but the standard term used for the force required to move a spring a specific distance is the spring rate. Load rating tells you how much load the spring can carry, and deflection is the amount of movement itself, not the force-per-distance metric.
