What “calculated on your device” means for this tool
When you open this page, your browser downloads the converter itself, the same way any web page loads. From then on, every conversion happens inside your browser, on your own device, and it works offline. The numbers you type are never sent to this website's server or to anyone else.
What is saved: the last units you picked, in this browser only, so they are ready next time.
Visit counting: this site counts visits with privacy-friendly analytics. No cookies, no ads, no tracking across other sites, and your IP address is not stored. It records which page you opened, your country, your device type and how long you stayed.
Conversions use exact international definitions (for example 1 inch = 2.54 cm, 1 pound = 0.45359237 kg). US and UK cups, pints and gallons are different sizes and are listed separately.
