Note · How this page is built
This index is generated at build time from the sources[] array on every calculator's content file. A single source cited by multiple calculators appears once with all citing calculators listed. When a calc adds or removes a source, this index rebuilds automatically.
Total citations across all calculators: 66. Total unique sources: 59. The difference is the reuse factor: sources that power more than one calculator.
Redline · scope notice Every source link goes directly to the publisher's official site. When a link breaks, report it to [email protected] and the calculator content will be updated in the next revision cycle.
