 • Surface power density has the dimension mass per time cubed. The SI composite unit of surface power density is the watt per square meter.
 • Maple knows the units of surface power density listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes langley power langleys SI

 An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, langley[power]; or, if the context is indicated as the default, by using only the unit name or symbol.
 The unit of surface power density is defined as follows.
 A power langley is defined as a thermochemical calorie per square centimeter minute.
