Way late for the asker I'm sure, but I was curious about this as well.
The distance between two degrees of longitude depend greatly on the value,
since the earth is, you know, a sphere. Latitude is pretty consistent though.
For these calculations I assumed we're at the equator. Below is a table of the
resolution (number of characters) in a geocell to the latitudinal (top to
bottom) distance in meters. Disclaimer: I wouldn't bet my life on these
figures, and neither should you.
13: 0.30
12: 1.19
11: 4.75
10: 18.98
9: 75.93
8: 303.70
7: 1,214.81
6: 4,859.22
5: 19,436.88
4: 77,747.54
3: 310,990.14
2: 1,243,960.57
1: 49,75,842.27
And here's the same table for longitude at the equator:
13: 0.60
12: 2.39
11: 9.55
10: 38.22
9: 152.87
8: 611.50
7: 2,445.98
6: 9,783.94
5: 39,135.75
4: 156,542.99
3: 626,171.95
2: 2,504,687.81
1: 10,018,751.22
And at 45 degrees latitude:
13: 0.42
12: 1.69
11: 6.77
10: 27.07
9: 108.28
8: 433.12
7: 1,732.47
6: 6,929.90
5: 27,719.58
4: 110,878.32
3: 443,513.28
2: 1,774,053.13
1: 7,096,212.51
