# Tension vs. Pressure: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Updated on October 18, 2023
Tension refers to the force that stretches or elongates something, while Pressure denotes the force exerted per unit area on a surface.

## Key Differences

Tension is a force that acts to expand or lengthen an object. Imagine pulling a rubber band between two fingers; the force you're applying is creating tension.

Pressure, in contrast, is concerned with how much force is applied over a given area. If you press your hand against a wall, you're exerting pressure on that wall.

When you hang a weight from a rope, the rope experiences tension because of the pulling force the weight exerts on it.

Yet, if you were to press that weight against a surface, it would exert pressure on that surface, which can be calculated by dividing the force it applies by the area over which it's distributed.

Tension commonly relates to materials like ropes, cables, and springs — objects that can be stretched or elongated.

In contrast, pressure is often discussed in contexts like fluid dynamics, meteorology (as atmospheric pressure), or even in social situations where one feels "under pressure."

In engineering, tension tests assess the strength and elasticity of materials to see how much they can be stretched before breaking.

Pressure tests, however, might evaluate the strength of containers or systems to hold or resist fluids or gases at different force intensities without rupturing.
