To reduce the costs and installation space of a rough weighing section for supplying weighed objects to a plurality of weighing devices.

A weighing system 11 of bar-shaped objects for weighing a plurality of bar-shaped weighed objects 12 by a predetermined target weight includes: a rough weighing section 13 for roughly weighing a volume of weighed objects 12 corresponding to a large weight smaller than the target weight; four weighing devices 14; and a conveyance device 30 for supplying the weighed objects 12 roughly weighed by the rough weighing section 13 to the four weighing devices 14 in state of being compactly put together. Each weighing device 14 includes: a precision weighing section 16 for precisely weighing the roughly weighed objects 12; a correction weight operation section for subtracting the precise weighing value obtained through weighing of the precision weighing section 16 from the target weight to calculate a correction weight value; and a correction weighing section 17 for weighing the weighed objects 12 by the amount of the correction weight value by using the weighed objects 12 roughly weighed by the rough weighing section 13.
