Practical tools
Last reviewed: April 25, 2026
This section gathers small interactive utilities that come up again and again when reading about the United States or moving there: distance, temperature, and currency converters, a searchable list of states and capitals, the U.S. time zones, and a filterable states map. Every tool works offline once the page is loaded, does not require an account, and stores nothing about you.
Each link below opens the working tool.
