    16.387 was from memory. 16.387064 would be more accurate.

      Morning Tom,
      I just singed up to the RP list and was reading some back postings and was curious
      where the 16.387 CC/CU Inch came from?
      Thanks,
      Miguel

      Whoops, Al, you are right!

      I re-ran my calculation, as follows:

      $200/lb (Perfactory resin) x 1lb/453.59 gm x 1.1 gm/cc x 16.387 cc/cu inch = $7.95/cu inch.

        Using your density number, I come up with 24 cu inches per pound or approximately $8 per cubic inch.
