889.90 squares is about four-fifths as big as a City Block (Manhattan)
In other words, it's 0.8 times the size of a City Block (Manhattan), and the size of a City Block (Manhattan) is 1 times that amount.
(per Bridges, William - 1811 Commissioner's Plan for New York City) (approximate) A Manhattan city block measures about 200 m between the Northeast-Southwest streets by about 60 m between the Northwest-Southeast streets for a total area of about 1,000 squares. There are roughly 2,000 blocks within the city, representing one of the most prolific applications of the city planning grid plan in history.
