Put the weight ranges in a MySQL table and use the BETWEEN operator to
retrieve the appropriate weight.

Something like:

fromweight, toweight, value
0,0.5,9.45
0.501,1.0,10.71
1.001,1.5,11.97

Then, the following SQL statement will pull the appropriate value:

SELECT value FROM weights WHERE 1.3 BETWEEN fromweight AND toweight


Much warmth,
