All values follow internationally accepted definitions and are rounded to the decimals you choose. The calculation runs entirely in your browser, so nothing is uploaded or stored on a server.
History & Background
The elegant unit "knot" originated in the great age of sail. Sailors threw a wooden board tied to a rope with knots over the stern and counted the knots that slipped into the water over a set time to calculate speed.
