Đổi đơn vị tốc độ

Where this converter helps

• Comparing road speeds in km/h and mph when planning travel or reading vehicle data.
• Converting knots for marine, aviation, and weather reports.
• Moving between m/s and ft/s for physics, engineering, and ballistics notes.

Using the interface

Enter the speed in the unit you have. The active field stays highlighted and every other card updates from metres per second as the base rate.

Practical notes

• Knots are nautical miles per hour and should be kept separate from mph.
• Metres per second is compact for scientific calculations; km/h and mph are easier for road travel.
• For pace calculations such as minutes per kilometre, use a dedicated pace tool rather than a speed unit converter.
