The sundial
In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stop watches are also used to measure time in some sports.
You would possibly use a chronometer which is an extrememely accurate clock.You would possibly use a chronometer, a very accurate clock.
You can measure kilometres in metres, which would be 1000, or decametres, that would be 100, or in hectometres, that's 10. You could even measure in decimetres

The traditional instrument used to measure the time of a given run is the stopwatch.
A compass is a scientific instrument used to locate the north magnetic pole. The magnetic changes in the Earth's core make the north magnetic pole move over time.
watches kind of like compasses!
That is called the reliability of the instrument. It refers to the consistency and stability of the measurements it provides over time.
A laser rangefinder is commonly used to measure short vertical distances accurately. It emits a laser beam to measure the time it takes for the beam to reflect off a target and return to the device, calculating the distance based on the speed of light.
