What is the SI unit of stress ?

What is the SI unit of stress ?

The velocity v of sound waves, through a medium may be assumed to depend on density of the medium, d and Modulus of elasticity (E) . Modulus of elasticity is a ratio of stress to strain and stress is force per unit area. Deduce by the method of dimensions the formula for the velocity of sound.
