    Convert a list in one unit to a list in another, using Pint.
    Simple but saves me from writing this repeatedly in ipython.
    <source> and <target> must be Pint units, e.g.
    >>> ur = pint.UnitRegistry()
    >>> convert([1, 2], ur.inch, ur.meter)
    [<Quantity(0.0254, 'meter')>, <Quantity(0.0508, 'meter')>]
    '''
    return  [Q(x, source).to(target) for x in array]
