In order to provide a technique by which a highly-accurate conversion rule of measurement values between different spectrocolorimetric devices can be easily set, the spectrocolorimetric device includes a light source, a light-receiving unit, and a conversion unit. The light-receiving unit spectroscopically disperses reflected light generated on a surface of an object according to irradiation of the object with illumination light emitted from the light source and measures a spectroscopic spectrum of the reflected light. The conversion unit calculates a spectral reflectance that can be acquired by another spectrocolorimetric device from the spectroscopic spectrum by using a calibrated spectral sensitivity of the other spectrocolorimetric device different from the spectrocolorimetric device and the spectroscopic spectrum.
