What a kilometer and a mile are
Both are units of length, which is what makes them convertible at all: the converter above works by taking your value to a single reference unit for that family and back out again, so the figure it gives is the same one the table shows, carried to more digits. Nothing is sent anywhere to compute it — the arithmetic runs in this page, in your browser.
