But people are forgetting the hover text that Bing returns (see 1st result).For the search "circumference of the earth"

Compare that with Google's results https://img.skitch.com/20110211-r3jmccgi1ejs24p1hbdnu69fwm.j... (courtesy of xentronium). For this query Bing's results are far better that Google's (they actually specify circumference at equator and poles, alerting you that it's not the same; Google doesn't).
Also if you add (in meters|in miles) to the query, you get similar results to Google's.
