Advertising. This site uses Google AdSense to display advertisements. Google and its partners may use cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this or other websites. You may opt out of personalized advertising by visiting Google Ads Settings. Third-party vendors' use of advertising cookies enables them and their partners to serve ads based on your visits to this site and other sites on the Internet.

Analytics. This site uses Google Analytics 4 to measure aggregate traffic — pages viewed, approximate country, device type and how visitors arrived. Google Analytics sets cookies and processes this data on our behalf; it does not receive anything you type into a calculator, since those values never leave your browser. You can opt out across all sites using the Google Analytics Opt-out Browser Add-on, or block analytics cookies in your browser settings.
