To provide a kinetic motion measuring device, having high flexibility so that the momentum of exercise goods can be measured regardless of kind of exercise goods.

This kinetic motion measuring device 10 includes a conversion table 20 for converting signals from sensors 6 to 9 and outputting the same, and a characteristic changing means 21 for changing the conversion characteristic of the conversion table according to user's operation. The conversion characteristic of the signal conversion table can be set to be suitable for a desired motion characteristic, and a common kinetic motion measuring device can be used regardless of the kind of exercise goods.
