      "a": "Multiply the value in miles per hour by 0.44704: meters per second = miles per hour × 0.44704. For example, 5 mph = 2.2352 m/s."

      "a": "Multiply by the inverse factor 2.236936292 (miles per hour = meters per second × 2.236936292), or use the meters per second-to-miles per hour page."
