The version referenced in this article has been published on 4 August 2017.
There are three sets of conversion factors:
- Condensed set:
This is the most frequently requested dataset by users, which comprises an abridged version of the full set of factors, designed to reduce the volume of information users have to navigate through to find the factors they want. Recommended for most, and new, users of conversion factors - Full set:
This is the full dataset of factors, which contains all of the available factors for the selected year, and is recommended for advanced users only due to the volume of information presented. - Flat file set:
This dataset contains the same information as the full set, but arranged for automated processes – available from 2014 onwards. Not recommended for most users
An accompanying methodology paper explains how the conversion factors are derived, which can be downloaded here
It is recommended for:
New users of the conversion factors to download the condensed set of conversion factors from the latest available year and read the guidance in the document’s introductory sheet and follow the informative text at the top of each conversion factor tab in the output files.
Advanced or repeat users of the conversion factors to download your preferred factor set and read the ‘what’s new’ sheet before using the conversion factors. This sheet highlights the most significant changes to the conversion factors made in this update. Following the ‘what’s new’ guidance will ensure that reporting is consistent and comparable year-on-year.
