convert(x, unit1, unit2) -> float:
'''
General method for doing unit conversions. He knows about scientific prefixes like G, M, and so on.
If the unit ends in 'inv', it is interpreted as 1/unit.

Args:
    x (float): measurement in [unit1]. 
    unit1 (str): Original units.
    unit2 (str): Target units.

Returns:
    float: measurement in [unit2].
