Conversion details
All calculations rely on the international standard of 1 inch = 25.4 millimeters. Decimal values are rounded to four places, fractional results use 1/32" increments with automatic simplification, and feet+inches formatting is ideal for dimensions above 300 mm. For higher precision, URL parameters, or bulk conversion needs, head back to the main calculator or batch converter.
At 17 mm (~0.6693 in), This is a small precision dimension. Fractional output (1/32") helps with fine workmanship; keep decimal inches for calculations and tolerance notes.
