Write the Unit and Dimension of Young’s Modulus of Elasticity – Complete Explanation
Write the Unit and Dimension of Young’s Modulus of Elasticity is a very important topic in Class 11 and Class 12 Physics. In this post we will learn the exact unit, SI system, dimensional formula and meaning of each term in a simple and exam-oriented way.
What is Young’s Modulus of Elasticity?
Young’s Modulus of Elasticity is a measure of stiffness of a material. It tells us how much a body will stretch or compress when a force is applied. It is one of the most important mechanical properties of solids.
Unit of Young’s Modulus (Focus Keyword)
The SI unit of Young’s Modulus is Pascal (Pa). It is also written as Newton per square meter (N/m²). In CGS system, the unit is dyne/cm².
SI Unit

Dimension of Young’s Modulus
The dimensional formula of Young’s Modulus is:
[M¹ L⁻¹ T⁻²]
This dimension clearly shows that Young’s modulus depends on mass, length and time.
Conclusion
Young’s Modulus of Elasticity plays an important role in engineering and physics. It helps to compare the stiffness of different materials and predict deformation. Remember that its unit is Pascal and dimension is M¹L⁻¹T⁻² which is very important for examinations.
