__init__()
add_context(context)	Add a context object to the registry.
as_system(system)	Temporarily change the current system of units

define(definition)	Add unit to the registry.
disable_contexts([n])	Disable the last n enabled contexts.
enable_contexts(*names_or_contexts, **kwargs)	Enable contexts provided by name or by object.
get_base_units(input_units[, check_nonmult, ...])	Convert unit or dict of units to the plain units.
get_compatible_units(input_units[, ...])
get_dimensionality(input_units)	Convert unit or dict of units or dimensions to a dict of plain dimensions dimensions
get_group(name[, create_if_needed])	Return a Group.
get_name(name_or_alias[, case_sensitive])	Return the canonical name of a unit.
get_root_units(input_units[, check_nonmult])	Convert unit or dict of units to the root units.
get_symbol(name_or_alias[, case_sensitive])	Return the preferred alias for a unit.
get_system(name[, create_if_needed])	Return a Group.
is_compatible_with(obj1, obj2, *contexts, ...)	check if the other object is compatible
load_definitions(file[, is_resource])	Add units and prefixes defined in a definition text file.
parse_expression(input_string[, case_sensitive])	Parse a mathematical expression including units and return a quantity object.
parse_pattern(input_string, pattern[, ...])	Parse a string with a given regex pattern and returns result.
parse_unit_name(unit_name[, case_sensitive])	Parse a unit to identify prefix, unit name and suffix by walking the list of prefix and suffix.
parse_units(input_string[, as_delta, ...])	Parse a units expression and returns a UnitContainer with the canonical names.
parse_units_as_container(input_string[, ...])
pi_theorem(quantities)	Builds dimensionless quantities using the Buckingham π theorem
remove_context(name_or_alias)	Remove a context from the registry and return it.
set_fmt_locale(loc)	Change the locale used by default by format_babel.
setup_matplotlib([enable])	Set up handlers for matplotlib's unit support.
with_context(name, **kwargs)	Decorator to wrap a function call in a Pint context.
wraps(ret, args[, strict])	Wraps a function to become pint-aware.
