A measurement system obtains its own measurement result through use of a different system's measurement result obtained by a different measurement system. The measurement system includes: an output data acquisition unit, a designated position acquisition unit configured to acquire a designated position, which is a position indicating an address at which the different system's measurement result is represented in the output data, by a user's designation, a different system's measurement result acquisition unit, a measurement result acquisition unit, and a position data storage unit configured to store position data indicating the designated position. The different system's measurement result acquisition unit acquires, when the position data is already stored in the position data storage unit in a case where the output data acquisition unit acquires different output data obtained by the different measurement system, the different system's measurement result included at the designated position indicated by the position data.
