Convert between unit systems

[mnesarco]

Hello Friends,
I have an internal model with mks units, but i want to present values to the user in a user selected unit system, so is there an easy way to present a quantity in an specific unit system base form?

for exampe:

from pint import UnitRegistry

u = UnitRegistry(system='mks')

x = 0.1 * u.km

print(x.to_base_units())
#> 100 meter

# !! Something like this:
print(x.to_base_units(system='imperial')) # <-- Not supported 
#> 328.0839895013123 feet

My current workaround is this but it feels a bit inefficient and verbose:

from pint import UnitRegistry

u = UnitRegistry(system='mks')
v = UnitRegistry(system='imperial')

x = 0.1 * u.km

print(v.parse_expression(str(x)).to_base_units())
#> 109.3613298337708 yard
