SUMMARY
Young's Modulus is expressed in gigapascals (GPa), which is a unit of pressure equivalent to 10^6 pascals (Pa). In the context of material science, stress is measured in kilonewtons per square meter (kN/m²), which is equivalent to kilopascals (kPa). Since pressure is defined as force per unit area, the relationship between stress and Young's Modulus confirms that E is indeed in kN/m² or kPa, which translates to GPa for larger values.
