  3. Metric time - Wikipedia

    en.wikipedia.org/wiki/Metric_time

    Metric time is the measure of time intervals using the metric system. The modern SI system defines the second as the base unit of time, and forms multiples and submultiples with metric prefixes such as kiloseconds and milliseconds. Other units of timeminute, hour, and day – are accepted for use with SI, but are not part of it

    The term "second" comes from "the second minute division of an hour", as it is 1 ⁄ 60 of a minute, or 1 ⁄ 60 of 1 ⁄ 60 of an hour. While usually sub-second units are represented with SI prefixes on the second (e.g. milliseconds), this system can be extrapolated further, such that a "Third" would mean 1 ⁄ 60 of a second (16.7 ...

    Tachymeter scale on a Citizen watch bezel. A tachymeter (pronounced / t æ ˈ k ɪ m ə t ər /) is a scale sometimes inscribed around the rim of an analog watch with a chronograph.It can be used to conveniently compute the frequency in inverse-hours of an event of a known second-defined period, such as speed (distance over hours) based on travel time (distance over speed), or measure distance ...

  7. Metre per hour - Wikipedia

    en.wikipedia.org/wiki/Metre_per_hour

    Metre per hour (American spelling: meter per hour) is a metric unit of both speed and velocity (Vector (geometry)). Its symbol is m/h or m·h −1 (not to be confused with the imperial unit symbol mph). By definition, an object travelling at a speed of 1 m/h for an hour would move 1 metre.

    The second is readily determined from the Earth's rotation period. Unlike other units, time multiples are not decimal. A second is ⁠ 1 / 60 ⁠ of a minute, which is ⁠ 1 / 60 ⁠ of an hour, which is ⁠ 1 / 24 ⁠ of a day, so a second is ⁠ 1 / 86 400 ⁠ of a day.
