Pears come in a range of sizes. In the United States the size is based on the number that will fill a 44 pound shipping box. The bigger the pear the fewer needed.
Pear sizes may range from 50 to 215 but in stores are usually from 70 to 150.

estimate of weight per fruit in ounces =
= (44 * 16) / (pear size by count)
estimate for size number =
= (44 * 16) / (weight in ounces)
A line approximation of the peer size number vs weight in ounces:
weight in ounces =
= (0.000685 * ((number)^2)) - (0.2302 * (number)) + 23.71
