Count tools separately from pages
1444 canonical searchable tools, plus 3,250 unit-pair conversion pages. Topic collections, aliases and redirects are not additional capabilities.
One topic destination
102 topic hubs connect related tools. Featured topics appear in navigation; equivalent category and tag archives share one canonical destination.
Preserve useful originals
All 345 original URLs have an explicit migration decision. Original working capabilities and 50 migrated control modes remain available; equivalent task pages redirect.
Understand verification
Each tool states its input limits and assumptions. Server tools require the installed processing service. Tests do not establish universal compatibility or live platform availability. No measured search-volume or ranking claims are made.
