0 to 60 mph. The time it takes a vehicle to accelerate from 0 to 60 miles per hour (97 km/h or 27 m/s ), often said as just " zero to sixty " or " nought to sixty ", is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used.
