San Francisco is 46.7 square miles = 121 kmsq (I think of it as 7 miles on a side = abt 50 sq. miles)
So, 50 square miles = about 32,000 acres = about 13,000 hectares.
1 acre = 40% of a hectare. A hectare is 100 meters on a side = 10,000 sqmeters.
An acre is 208 feet on a side (as opposed to 100 meters).</p>
<p>
There are 100 hectares in a square kilometer.</p>
<p>
1 sq mile = 2.58998 sq kms. Call it 2.6 sq kms.</p>
<p>
Stanford University owns 8,183 acres = 32 km2 = abt 13 sq miles.</p>
<p>
San Francisco is about 4 * the size of Stanford. (12 * 4 = 48 sq miles)
