Electric resistivity has the dimension length cubed mass per time cubed electric current squared.  The SI compound unit of electric resistivity is the ohm meter.

Maple knows the units of electric resistivity listed in the following table.

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, preece[resistivity]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, preece.

The unit of electric resistivity is defined as follows.

A resistivity preece is defined as a resistance preece standard quadrant.

$\mathrm{convert}\left('\mathrm{preece}\left[\mathrm{resistivity}\right]'\,'\mathrm{dimensions}'\,'\mathrm{base}'=\mathrm{true}\right)$

$\frac{{\mathrm{length}}^3\mathrm{mass}}{{\mathrm{time}}^3{\mathrm{electric\_current}}^2}$

$\mathrm{convert}\left(1\,'\mathrm{units}'\,'\mathrm{preece}\left[\mathrm{resistivity}\right]'\,'\mathrm{\Omega }''m'\right)$

$10000000000000$

$\mathrm{convert}\left(1\,'\mathrm{units}'\,'\mathrm{preece}\left[\mathrm{resistivity}\right]'\,'\mathrm{preece}\left[\mathrm{resistance}\right]''\mathrm{quadrant}\left[\mathrm{standard}\right]'\right)$
