Frequently asked questions
- When should I use millimetres instead of inches?
- Millimetres in engineering, 3D printing and metric tolerances. Inches for pipe threads, imperial tooling and US hardware specs.
- Can the result be negative?
- No — length and tolerance values are positive.
- How precise is the result?
- 1 in = 25.4 mm exactly. On small dimensions every decimal matters.
- What is the most common input mistake?
- Rounding 1 inch to 25 mm instead of 25.4 mm — errors stack on repeated holes or fits.
