A knot is one nautical mile per hour. Do not substitute a statute mile when checking marine or aviation speeds.
Speed Converter is for this task: Convert m/s, km/h, mph, ft/s, and knots quickly. It runs in the browser; start with a short, non-sensitive sample and confirm the behavior before processing more data.
Use it for a focused Speed Converter task when a quick browser workbench is appropriate.
