Convert Metric to Standard for Cooking Sewing Machine Diagram

Biological diagram infographic titled "Sewing Machine Parts" centered on a clean labeled diagram of a technically accurate domestic sewing machine in editorial-grade cross-section / cutaway style, treated as a mechanical anatomy infographic. Show the machine in side-perspective with key external and internal components clearly visible. Mark 9 labeled parts, each with a thin leader line, a short label in English, and a one-line function description in English: "Spool Pin" — "Holds the thread spool for feeding."; "Thread Guide" — "Directs upper thread toward the tension path."; "Tension Discs" — "Regulate upper thread tension for balanced stitches."; "Take-Up Lever" — "Feeds and retracts thread during stitch formation."; "Needle Bar" — "Moves the needle up and down precisely."; "Presser Foot" — "Holds fabric flat against the feed mechanism."; "Feed Dogs" — "Advance fabric evenly between stitches."; "Bobbin Case" — "Houses lower thread for lockstitch formation."; "Handwheel" — "Manually controls the main drive motion." Include a small legend panel with simple line icons for moving thread path and stitch zone, but no brand logos and no unrelated search-intent text. Visual style: blueprint technical drawing, industrial neutral palette with navy-blue background, white and light gray vector linework, muted steel accents, precise drafting marks, subtle grid, calm instructional mood. Emphasize technical accuracy, balanced spacing, readable callouts, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks Technically accurate parts. No real tool-brand logos.
