132 views

Kilometers per hour per second (km/h/s) is a unit of acceleration. It measures the change in velocity (in km/h) for each second. For example, if a car accelerates from 0 to 60 km/h in 5 seconds, its acceleration is 12 km/h/s.

FAQs & Answers

  1. What is kilometers per hour per second (km/h/s)? Kilometers per hour per second (km/h/s) is a unit of acceleration that measures how much the speed changes in kilometers per hour every second.
  2. How do you calculate acceleration in km/h/s? To calculate acceleration in km/h/s, divide the change in speed (in km/h) by the time in seconds during which the change occurs.
  3. Is km/h/s a common unit for acceleration? Km/h/s is less common than meters per second squared (m/s²) but is sometimes used for practical examples like car acceleration where speed is often measured in km/h.
  4. How does km/h/s relate to m/s²? To convert km/h/s to m/s², multiply the value by 0.27778 since 1 km/h equals approximately 0.27778 meters per second.
