UnrecognizedUnit
(st, doc=None, format=None, namespace=None)[source] [edit on github]¶ Bases:
astropy.units.IrreducibleUnit
A unit that did not parse correctly. This allows for round-tripping it as a string, but no unit operations actually work on it.
Parameters: - st : str
The name of the unit.

get_format_name
(format)Get a name for this unit that is specific to a particular format. is_equivalent
(other[, equivalencies])Returns True
if this unit is equivalent toother

get_format_name
(format)[source] [edit on github]¶ Get a name for this unit that is specific to a particular format.

format
kwarg in the constructor.Parameters: - format : str
The name of the format
Returns: - name : str

is_equivalent
(other, equivalencies=None)[source] [edit on github]¶ Returns
True
if this unit is equivalent toother
.Parameters: - other : unit object or string or tuple
The unit to convert to. If a tuple of units is specified, this method returns true if the unit matches any of those in the tuple.
- equivalencies : list of equivalence pairs, optional
A list of equivalence pairs to try if the units are not directly convertible. See Equivalencies. This list is in addition to possible global defaults set by, e.g.,
set_enabled_equivalencies
. UseNone
to turn off all equivalencies.
Returns: - bool
