Precautionary guidance
- Keep the source unit consistent with the spec or drawing.
- Use ft+in only for inputs that include both values.
- Maintain precision until final reporting or machining.
- Document conversions alongside revision notes.
- Confirm nautical vs statute miles for navigation.
- Recalculate if units change in upstream documents.
Keep conversions attached to spec sheets and routing notes.
