In a method of measuring a viscosity of a sample based on a rotation frequency &OHgr;S of a conductive rotator rotating by applying a rotating magnetic field from outside to the rotator set in a container containing the sample and a rotation frequency &OHgr;B of the magnetic field, a constant k1 having temperature dependency of an apparatus and a constant k2 not having the temperature dependency at each temperature are found by using a equation, &eegr;0&OHgr;s=k1(&OHgr;B−&OHgr;S)−k2, where a viscosity &eegr;0 at specific temperature is known, and then a value of viscosity measured at the specific temperature is corrected by means of the constants k1 and k2, the rotation frequency &OHgr;S of the rotator, and the rotation frequency &OHgr;B of the magnetic field. The constant k1 may employ the temperature dependency of electric conductivity of metal used to the rotator. |
