The ultimate tensile strength of a single-layer sheet of graphene is 1.30 × 1011 Pa.

The ultimate tensile strength of high-strength structural steel is 4.05 × 108 Pa.

Calculate the ratio:

ultimate tensile strength of grapheneultimate tensile strength of structural steel \frac{\text{ultimate tensile strength of graphene}}{\text{ultimate tensile strength of structural steel}} ultimate tensile strength of structural steelultimate tensile strength of graphene​
