METHODOLOGY FOR
DETERMINING CALIFORNIA AGRICULTURAL EXPORTS:
Data to compute
agricultural exports are derived from official government
sources, published industry sources and unpublished information
from government and industry. Total US export quantities
and values and California port exports are from Department of
Commerce trade data posted on the United States International
Trade Commission online database. Canadian import data
are from the Statistics
Canada online database. Production quantities and
values are from various National Agricultural Statistics Service
(NASS) and Economic Research Service (ERS) Publications.
Export data were
converted into Metric Tons (MT) or Hectoliters (HL).
Conversions: 1
MT = 2204.622 pounds; 1 gallon = 0.037853 HL; 1 short ton=2000
pounds; 1 cwt=100 pounds
