Definition Of chronometer


an instrument for measuring time, especially one designed to keep accurate time in spite of motion or variations in temperature, humidity, and air pressure. Chronometers were first developed for marine navigation, being used in conjunction with astronomical observation to determine longitude.

The process of mapping itself, now much more accurate thanks to Britain's invention of the chronometer for measuring longitude, allowed the British to perceive the globe as an integrated whole.
