About Percent Strain (%)
Strain expressed as percentage of original length (ε × 100%) — the default reporting unit on every tensile-test stress-strain curve in materials-science publication, materials-property databases (MatWeb, NIST MMP, Granta Selector, MMPDS), and ASM Handbook material data sheets. Used universally for: yield strain (aluminum 6061-T6 yields at ~0.5% strain, mild structural steel yields at 0.2% strain — the basis of the 0.2% offset yield-strength definition per ASTM E8/E8M), elongation at break per ASTM E8 (the percent value shown on every metal's data card — 6061-T6 has 12% elongation at break, mild steel 25-30%, brass alloys 30-65%, polyethylene 100-700%, EPDM rubber 300-600%), and fracture-toughness J-integral analysis. Steel-reinforced concrete strain limits per ACI 318: tension steel must reach ε ≥ 0.005 (0.5%) for tension-controlled design.
About Millimeter per Millimeter (mm/mm)
Strain expressed as millimeters of deformation per millimeter of original length — numerically identical to unitless strain ε and to in/in ratio, but the explicit mm/mm notation clarifies that the quantity is a length ratio derived from a metric-units gauge length. Common on European / Asian / Australian metric-edition engineering drawings (per ISO 128 technical-drawing standards), material property sheets from European steel mills (ArcelorMittal, Tata Steel, voestalpine, ThyssenKrupp), DIN material specifications (DIN EN 10025 hot-rolled structural steel, DIN EN 10088 stainless steel), and CAD-software material-property output. Identical to unitless strain numerically (1 mm/mm = 1.000 = 100% strain), so the choice between mm/mm and unitless is stylistic for clarity in tabulated metric data. Used in mechanical-properties tables, FEA strain-output post-processing (Ansys Mechanical, ABAQUS, NASTRAN report strain output as mm/mm in metric-units projects), and structural-health-monitoring records.

Understanding Percent Strain
The Percent Strain (symbol: %) is a unit of strain. Strain expressed as percentage of original length (ε × 100%) — the default reporting unit on every tensile-test stress-strain curve in materials-science publication, materials-property databases (MatWeb, NIST MMP, Granta Selector, MMPDS), and ASM Handbook material data sheets. Used universally for: yield strain (aluminum 6061-T6 yields at ~0.5% strain, mild structural steel yields at 0.2% strain — the basis of the 0.2% offset yield-strength definition per ASTM E8/E8M), elongation at break per ASTM E8 (the percent value shown on every metal's data card — 6061-T6 has 12% elongation at break, mild steel 25-30%, brass alloys 30-65%, polyethylene 100-700%, EPDM rubber 300-600%), and fracture-toughness J-integral analysis.
