The Trade Analyser and Units of Measurement

The metadata are not always conveniently located with the data, which can lead to problems. Here is an example of trying to understand the units of measurement associated with statistics from the Trade Analyser.

A patron was referred to the Data Library from the Business Reference Desk. She was using the Trade Analyser database, which is supported online through CHASS at the University of Toronto. She had retrieved some statistics for the quantity and value of fruit puree imported to Ontario from California. The statistics, however, were listed without reference to their unit of measurement. She wanted to know the unit used for the quantity of fruit puree imported. Is it pounds, tonnes, kilograms, or some other weight or volume measurement?
