PURPOSE:To achieve accurate weight measurement, by arranging an air density measuring sensor in a measuring device or as connected thereto to output a measured value of air density to a weight measuring section as correction value. CONSTITUTION:A pressure sensor 1, a temperature sensor 2 and a moisture sensor 3 are arranged at a specified position near a measuring device not illustrated to input the results of measurement of the sensors into a digital computation circuit 6 for calculating air density in the measuring device. An air density calculated with the circuit 6 is outputted to a digital computation circuit 9 for measuring weight as correction value. This allows the correction of effect on an object to be measured of a buoyance due to air density thereby assuring accurate weight measurement.
