Decimeters to Millimeters Converter
Batch convert decimeters (dm) to millimeters (mm) with smart text parsing. Ideal for drafting, CAD design, and manufacturing blueprint scaling.
About
Drafting and manufacturing workflows often require seamless transitions between metric sub-units. While millimeters serve as the standard for precision engineering, decimeters frequently appear in older blueprints, educational models, or European architectural sketches as an intermediate scale. The conversion involves a shift of two orders of magnitude.
Misinterpretation of these scales leads to significant fabrication errors. A factor of 100 difference means a 1.5 dm part becomes 150 mm, not 15 mm. This tool addresses the specific need for batch processing in CAD data migration and bill of materials (BOM) auditing. It employs a parsing engine capable of extracting numerical values from mixed-text strings, allowing users to paste raw specification lists directly without manual cleaning.
Formulas
The relationship between the decimeter and the millimeter is defined by the base-10 metric system structure. One decimeter represents one-tenth of a meter, while one millimeter represents one-thousandth of a meter.
To reverse the calculation (millimeters to decimeters), divide by the magnitude factor:
