Beamon's jump was a world record that eclipsed the previous record by 21 3/4 inches. The jump still stands as an Olympic record, and stood as a world  record until Mike Powell leapt 29' 4 1/2" at the 1991 World Championships in Tokyo.
Mike Powell leapt 895.35 cm at the 1991 World Championships in Tokyo.
29' 4 1/2" is equal to 895.35 cm. The system probably doesn't understand unit conversions.
