_separatePrefix(units)

alpha_e(year=2018, returnErr=False)

Fine structure constant. 

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].

fm_to_MeVinv(x) -> float

fpi_phys(year=2018, units='MeV', returnErr=False)

Physical value of the pion decay constant, f_pi+/-. 

frho_phys(year=2017, units='GeV', returnErr=False)

Physical value of the rho decay constant. 

lambda_MSbar_phys(year=2021, units='MeV', returnErr=False)

Physical value of MS-bar lambda parameter. 

r0_phys(year=2014, units='fm', returnErr=False)

Physical value of Sommer scale r0. 

r1_phys(year=2010, units='fm', returnErr=False)

Physical value of Sommer scale r1.
