About this tool
The speed converter changes values between metres per second, kilometres per hour, feet per second, miles per hour, and knots. Use it to compare road speeds, running or cycling pace, and nautical measurements. Enter a decimal value, select the source and target units, and convert. Metric, imperial, and nautical labels stay visible throughout the calculation, making it easier to confirm that the copied result uses the intended scale.
