 Parameters
 units:
str
orre.Pattern
orUnits
, optional Units to be compared.
Units are specified by a string (e.g.
'm s1'
), or a compiled regular expression (e.g.re.compile('^m')
), or aUnits
object (e.g.Units('m s1')
).If no units are provided then there is always a match.
 exact:
bool
, optional If False then a match occurs if the construct’s units are equivalent to any of those given by units. For example, metres and are equivalent to kilometres. By default, a match only occurs if the construct’s units are exactly one of those given by units. Note that the format of the units is not important, i.e. ‘m’ is exactly the same as ‘metres’ for this purpose.

 Returns
bool
Whether or not there is a match.
Examples
>>> f.units 'metres' >>> f.match_by_units('metres') True >>> f.match_by_units('m') True >>> f.match_by_units(Units('m')) True >>> f.match_by_units('m', 'kilogram') True >>> f.match_by_units('km', exact=False) True >>> f.match_by_units(cf.Units('km'), exact=False) True >>> f.match_by_units(re.compile('^met')) True >>> f.match_by_units(cf.Units('km')) False >>> f.match_by_units(cf.Units('kg m2')) False
