Agricultural Conversion Factors


In cooperation with the Economic Research Service of the USDA, The Food Industry Center updated the Agricultural Conversion Factors for specified agricultural products.

Conversion Factors refer to the yield, or the percentage of the raw commodity, leaving the farm gate that ends up as fresh or processed consumer product at the retail level. This widely used USDA data series of product specific conversion factors plays a crucial role in:

  • Developing supply and disappearance balance sheets for agricultural products, Calculating the food available for consumption and per capita food availability (i.e., proxies for actual food consumption), 
  • and determining Federal policy for food and agricultural markets and for human health and nutrition.


The Conversion Factors were updated because:

  • many of the Conversion Factors have not been substantially updated since the1960’s;
  • the most recent documentation of the Conversion Factors was published in 1992 in Weights, Measures, and Conversion Factors for Agricultural Commodities and their Products;
  • the form in which many of these products are available to consumers has changed since the Conversion Factors were last revised.

This website has been created to share the Conversion Factors information provided by industry, academic and governmental units. The accuracy and appropriateness of the numbers presented will be improved by continued cooperation and review from knowledgeable professionals. The Center completed research on the following commodities:
