We employ the prescription of describing internal magnetic field in the vortex lattice by Hao {\\it et al.} and by Yaouanc {\\it et al.} to derive a torque formula as a natural extension of a preceding London theory. In marked contrast with the preceding model, our novel formula does not contain a phenomenological parameter $\\eta$, which prevents us from obtaining a {\\it true} upper critical field $H_{\\rm c2}$ by analyzing an experimental torque curve.
