As you pointed out well, the steric hindrance is just a relative value and not a precise measurement of the steric strains. It is usually manifested in intermolecular reactions, whereas discussion of steric effects often focus on intramolecular interactions.

Like, to give a simple, hypothetical example, $\ce{ch4}$ is said to have no steric hindrance. Steric hindrance is a broad definition and it occurs when atoms or groups are close to one another and there is an increase in energy because of the repelling electron clouds.

A Lot Is Known About Chemistry By Its Formula.

Steric hindrance at a given atom in a molecule is the congestion caused by the physical presence of the surrounding ligands, which may slow down or even prevent reactions at the atom. This kind of bimolecular attack that defines sn2 reactions can take place easily in primary electrophiles, or even on secondary ones. Steric hindrance is the stopping of a chemical reaction which might be caused by a molecule's structure.

Steric Hindrance And How It Affects Whether A Molecule Will Participate In An Sn2 Reaction.

Steric hindrance between adjacent groups can also affect torsional bond angles. (chemistry) any of several effects, most common in organic chemistry, in which the structure or reactivity of a molecule is affected by the physical size and proximity of neighbouring parts of the molecule. This can cause reactions to either slow down or stop completely with respect to the atom.
