The reciprocal of impedance is admittance, whose SI unit is the siemens, formerly called mho. According to Maver the term "mho" was suggested by Sir William Thomson (Lord Kelvin). This means that the FRO is usually smaller than the MHO. Released on her own label MHO, the album features songs written by Mie herself. His patients fondly called him "Mho Chao Fa" ('Doctor Prince').
