PROBLEM TO BE SOLVED: To provide a gas divided measuring system for divided-measuring the gas used amount corresponding to an actual gas used state by suppressing the integration error by a long-time counter. SOLUTION: This divided measuring system 4 built in a display device 3, based on the gas flow rate supplied from a gas meter 2 side, integrates the gas used amount by a gas appliance for hot-water supply with a large-flow-rate counter 42, integrates the gas used amount by a gas appliance for heating with a long-time counter 43, and integrates the gas used amount by a gas appliance for a kitchen with a normal counter 44. A divided measuring control section 41 stops the integration by the long-time counter 43 on months of May to September when the gas appliance for heating is not used, and switches the integration condition of the long-time counter 43 to a severe side on transition months (April and October) between used months (November to March) and non-use months of the gas appliance for heating.
