Units of Heat Insulation

Description

 • Heat insulation has the dimension time cubed thermodynamic temperature per mass. The SI composite unit of heat insulation is the second cubed kelvin per kilogram.
 • Maple knows the units of heat insulation listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes clo standard * clos Rvalue standard * Rvalues RSI @ SI tog standard * togs

 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, tog[standard]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, tog.
 The units of heat insulation are defined as follows.
 A clo is defined as $0.18$ degree Celsius meter squared hour per 15 degree Celsius kilocalorie.
 A standard R value is defined as $1$ square foot degree Fahrenheit hour per international table Btu.
 An SI R value (RSI) is defined as $1$ square meter kelvin per watt.
 A tog is defined as $0.1$ square meter kelvin per watt.

Examples

 > $\mathrm{convert}\left('\mathrm{tog}','\mathrm{dimensions}','\mathrm{base}'=\mathrm{true}\right)$
 $\frac{{{\mathrm{time}}}^{{3}}{}{\mathrm{thermodynamic_temperature}}}{{\mathrm{mass}}}$ (1)
 > $\mathrm{convert}\left(1,'\mathrm{units}','\mathrm{tog}',\frac{{'s'}^{3}'K'}{'\mathrm{kg}'}\right)$
 $\frac{{1}}{{10}}$ (2)
 > $\mathrm{convert}\left(1,'\mathrm{units}','\mathrm{clo}',\frac{{'s'}^{3}'K'}{'\mathrm{kg}'}\right)$
 ${0.1548091165}$ (3)
 > $\mathrm{convert}\left(1,'\mathrm{units}','\mathrm{clo}','\mathrm{tog}'\right)$
 ${1.548091165}$ (4)
