How long is 1 unit of time?

Answer 1

That depends on which unit you're talking about.

In general, the name of the unit indicates its length.

The following list gives some common units of time. Each item

on this list is longer than the one listed before it on this list.

-- nanosecond

-- microsecond

-- millisecond

-- second

-- minute

-- hour

-- day

-- week

-- fortnight

-- month

-- year

-- century

-- millennium

-- eon

Answer 2

If you are referring to a second of arc (1/3600 °) the radius of the arc is needed. Then there will be:

Minute_of_arc = 1/3600 × 1/360 × 2π × radius = π/648000 × radius

(where the radius is measured in mm).

Otherwise it is an impossible conversion to make, as mm (millimeter) is a measure of length while a second is a measure of time. This question could make sense if it were referring to how many millimeters an object travels in a second, but to answer that, we would need to know its speed.

Answer 3

The length of one unit of time is not fixed, as it can vary depending on the context in which it is being used. For example, in the metric system, one unit of time could be a second, minute, hour, day, etc.
