Young's modulus is defined as the ration of stress to strain for a given material below the limit of proportionality (the elastic limit). So Young's modulus is calculated by the formula: Stress/Strain is equal to young's modulus. Stress is defined as the force per unit area of cross-section below the limit of proportionality. So the formula is: Force (in newtons)/ Cross sectional area (in square metres). This would give the units Newtons per square metre which is written Nm-2 which is exactly the same as the Pascal (Pa); either can be used. Strain is defined as the fractional change in length produced when a body is subjected to stress. It's formula is: Change in length produced (in metres)/ Original legth (in metres). There are no units as it is a ratio of two values that have the same unit. So Young's Modulus has the formula: (Force/area)/(change in length/original length). This can be simplified to Stress/Strain (the amount of stress a body has to undergo to produce a certain amount of strain. The unit for stress is the Pascal (Pa) and there are no units for strain so overall, the unit for Young's Modulus is the Pascal (Pa) or Nm-2.
I think you mean "What variables affect young's modulus". Obviously not an english major!
young modulus remain unaffected ...as it depends on change in length ..
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.

Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
Metal is not a specific material, how is this ever going to be answered?!
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
The Young's modulus of Teflon (PTFE) is around 500-650 MPa, indicating its stiffness and resistance to deformation under stress.
The unit of measurement for the elastic modulus is pascals (Pa).
