The template supports calculation of inflation. A second parameter can be used to specify a year from 1800 onwards and the relative value in 2024 will be calculated.
A third parameter |about=yes will cause the template to calculate to the nearest dollar (instead of the nearest cent), and prefix the calculated value with "about". The rounding can be fine-tuned further by using |round=integer. These parameters may be combined.
Examples:
{{US$|10|1935}} → US$10 ($18.648 v 2024)
{{US$|10|1935|about=yes}} → US$10 (about $186 v 2024)
{{US$|10|1935|round=0}} → US$10 ($186 v 2024)
{{US$|1000|1935|round=2}} → US$1.000 ($1.864.806 v 2024)
{{US$|1000|1935|round=-2}} → US$1.000 ($18.600 v 2024)
{{US$|1000|1935|round=-2|about=yes}} → US$1.000 (about $18.600 v 2024)
Link
The parameter |link=yes may be used to link US$ to the article United States dollar. This is turned off by default, but may be appropriate for the first occurrence of the term in an article.
