Speed units split the world by who measures what, a European reader, an American reader, a pilot, and a physicist each want a different number. The conversion between them never changes, which is exactly why it should be a tool.
Convert speed between miles per hour, kilometers per hour, knots, and meters per second. Use it for recipes that mention running pace, flight manuals, and sports stats that arrived in a unit you do not think in.
