PROBLEM TO BE SOLVED: To provide a heating value measuring system capable of easily measuring a heating value of natural gas.;SOLUTION: A natural gas heating value measuring system comprises: a microchip 8 which includes a heating element generating heat at a plurality of heating temperatures; a formula storing device 402 which stores a heating value calculation formula in which an electric signal from the heating element at the plurality of heating temperatures is used as an independent variable, and a heating value is used as a dependent variable; a measuring part 301 which measures a value of the electric signal from the heating element generating heat at each of the plurality of heating temperatures and contacting gas; a heating value calculating part 305 which calculates a measured heating value of the gas, by assigning the measured value of the electric signal from the heating element to the independent variable of the heating value calculation formula; a correction value storing device 405 which stores a correction value which is a difference between a heating value of methane gas and a measured heating value of the methane gas, which is calculated by the heating value calculation formula; and a correcting part 307 which adds the correction value to the measured heating value of the methane gas, which is calculated by the heating value calculating part 305.;COPYRIGHT: (C)2014,JPO&INPIT
