About Inch per Inch (in/in)
Strain expressed as inches of deformation per inch of original length. Numerically identical to unitless strain and to mm/mm, but the in/in notation is the US engineering convention — US material data sheets (for alloys like 6061-T6 aluminum or 4140 steel) often list elongation at break in in/in alongside percent.
About Millimeter per Millimeter (mm/mm)
Strain expressed as millimeters of deformation per millimeter of original length. Numerically identical to unitless strain, but the explicit mm/mm notation clarifies that the quantity is a length ratio, which is common on metric-edition engineering drawings and material property sheets.
