      Relation Between Thou and Millimeter (mm)

      Let me explain to you about the relation between Thou and Millimeter (mm) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Thou ?

      A thou is a unit of length equal to 1/1,000 of an inch. Thou is a unit of length measurement which is commonly used in Length measurement. Used in engineering and manufacturing for tolerances and precision. Also known as a mil. Highlights small variations in measurements..

      What is Millimeter (mm)?

      Thou is another unit of length measurement that is used in Nanoengineering. A millimeter is a unit of length equal to 10−3 meters.. Used in engineering and manufacturing for tolerances and precision. Also known as a mil. Highlights small variations in measurements..

      How to Convert Millimeter (mm)?

      The conversion between Thou and Millimeter (mm) follows a simple formula:

      Thou = Thou × 0.0254

      Where, 0.0254 is the value that allows you to convert between Thou and Millimeter (mm).

      So,

      1 Millimeter = 0.0254 Thou

      And, 1 Thou = 1/0.0254 Millimeter
