SpeedConvert: Unit Converter

SpeedConvert is a fast, beautiful speed unit converter built for anyone who needs to switch between units quickly. Whether you are an engineer, student, pilot, driver, or just curious — SpeedConvert gives you instant, accurate results with a stunning animated speedometer interface.
Convert between all major speed units
Enter any value in kilometres per hour, miles per hour, metres per second, knots, or Mach and instantly see all other values update in real time. Tap any result to flip it into the input — no retyping needed.
Animated speedometer gauge
A smooth animated arc gauge tracks your input speed visually. The needle and arc change colour based on your speed zone, from green for walking speeds all the way to red for supersonic values.
Speed zones
SpeedConvert automatically labels your speed: Stationary, Walking or Slow, City or Road, Highway or Train, Aircraft, and Supersonic. A clear colour-coded badge updates with every conversion.
Speed reference table
The built-in reference table lists real-world speeds from walking pace to the speed of sound so you always have context.
