All quantities used (or sold) must be reported using one of the accepted units of measure. These units are all clearly defined units for weight or volume. Reporting quantities as “EA”, “BLOCK”, “STATION”, or similar descriptive units is not acceptable. Convert all such quantities to acceptable units.

If you need assistance locating the correct conversion factors, contact us.
