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.
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.

Understanding Millimeters per Millimeter
The Millimeter per Millimeter (symbol: mm/mm) is a unit of strain. 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.

It belongs to the metric measurement system.
Millimeters per Millimeter are commonly used in structural analysis, material testing, and geotechnical engineering.
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.
