How to Convert Acceleration from Meters Per Second Squared to Kilometers Per Hour Squared

Acceleration measures how quickly an object gains speed and is represented as distance divided by time squared. Units used to express acceleration include meters per second squared and kilometers per hour squared. If you want to compare how quickly two objects are gaining speed, but their accelerations are measured in different units, you need to convert to accurately compare. You can convert by knowing that there are 1,000 meters in 1 km and 12,960,000 seconds squared per hour squared.

      Divide the acceleration in meters per second squared by 1,000 to convert to kilometers per second. For example, if your acceleration is 5 m/s^2, divide 5 by 1,000 to get 0.005 km/s^2.

    • 2

      Multiply the acceleration in kilometers per second squared by 12,960,000 to convert to kilometers per hour squared. In this example, multiply 0.005 km/s^2 by 12,960,000 to get 64,800 km/h^2.
