Keywords: Radiation, Units
1 Purpose and scope
1.1 This Engineering Practice provides the SI units of measurement associated with quantities useful in describing all types of radiation for agricultural engineering applications. As an aid in establishing uniformity in the agricultural engineering literature, it also provides the generally accepted symbols which represent those quantities and the approved symbols for the units of the SI system applicable to those radiation quantities. The principal customary units that have been used for radiation quantities are also listed and factors are provided for conversion of those customary units to SI units.
