It means how "stiff" the spring is; how hard it is to compress or extend it.

SPRING BALANCEA spring balance apparatus is simply a spring fixed at one end with a hook to attach an object at the other. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore the scale markings on the spring balance are equally spaced.Spring balance can be used in physics and education as basic accelerometers, but its main uses are industrial, especially related to weighing heavy loads such as trucks, storage silos, and material carried on a conveyor belt. Spring balance are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness. A spring balance measures the weight of an object by opposing the force of gravity with the force of an extended spring. Spring balances measure weights in Gram as well as NewtonThe first spring balance in Britain was made around 1770 by Richard Salter of Bilston, near West Bromwich.[1] He and his nephews John & George founded the firm of George Salter & Co., still notable makers of scales and balances, who in 1838 patented the spring balance. They also applied the same spring balance principle to steam locomotive safety valves, replacing the earlier deadweight valves.[1]
There is no spring caliper.
The ratio of force applied to how much the spring streches (or compresses). In the SI, the spring constant would be expressed in Newtons/meter. A larger spring constant means the spring is "stiffer" - more force is required to stretch it a certain amount.
elaborate
Let's say you compress the spring. Work (mechanical energy) is required to compress the spring; this energy is stored in the spring and can be recovered (converted to another type of energy) when the spring returns to its normal position.
Yes, you have to compress if you remove either.

Weighing things.
Spring rate is the ammount of force it takes to compress a spring to a given height.
Forces Acting on Truss BridgesThere are two major forces that act on bridges: compression and tension. The compression force bears down on an object to shorten or compress it, while tension is the directly opposing force that lengthens and stretches the object. A spring is a good example of a simple mechanism that works with both forces. Compression pushes the coils together, thus shortening the spring and tension pulls the coils further apart, lengthening the spring
kinetic energy
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
Normally, yes.
you can measure how much water you watered your plant.
