Essential storage
A small preference value records whether you selected essential-only or accepted optional categories. It is required to remember your choice and does not track activity across other websites.
Analytics
Google Analytics is optional and loads only after you choose Accept all. It helps us understand page views, tool usage, device and browser information, and approximate location in aggregated reports. Our integration does not send the values you enter into calculators or converters. Google Analytics may set cookies whose names begin with _ga.
Advertising
Advertising spaces are placeholders only. No advertising network or personalised advertising cookie is active in this release.
