IRES Wiki

Units and Conversion — Map of Content

This MOC explains how IRES expresses, compares, and converts energy quantities. It connects original measurement units and the International System of Units with common energy units, calorific-value methods, default reference factors, conversion tables, and dissemination recommendations (IRES Ch. IV, Annex B).

Each annotation describes what its linked page defines, distinguishes, calculates, tabulates, or recommends. Start with measurement units for the unit system and conversion framework, then follow the calorific-value or dissemination pages that match the quantity and reporting task.

Concepts

  • Measurement Units - explains original and common units, defines SI measures for mass, volume, density, gravity, and energy, recommends the joule for cross-product comparison, and supplies the Annex B conversion grids
  • Calorific Values - distinguishes gross from net and default from specific calorific values, explains weighted-average calculations, and compares gross/net differences by fuel
  • Default Calorific Values - tabulates IRES default net calorific values, explains fuelwood, charcoal, and bagasse determinations, and supplies the Annex B moisture, charcoal-conversion, and waste-calorific tables
  • Units Recommended for Dissemination - distinguishes national collection freedom from dissemination recommendations, maps product categories to dimensions and units, and explains the recommendation to report physical quantities with specific calorific values

Entities

  • International System of Units - traces SI governance and adoption through the CGPM and BIPM and explains how its base units, prefixes, and joule underpin IRES’s original- and common-unit conventions

Sources

  • IRES Chapter IV — Measurement Units and Conversion Factors - explains the original/common-unit framework, develops IRES’s calorific-value methods, and compiles the chapter’s conversion and dissemination recommendations (IRES Ch. IV)
  • IRES Annexes and References - reproduces Annex B’s eight tables for mass, volume, and energy conversion, gross/net differences, fuelwood and charcoal determination, and waste calorific values (IRES Annex B)
