To convert ms to seconds: divide by 1,000. To convert seconds to ms: multiply by 1,000.
1 ms = 0.001 s = 1,000 µs = 10⁶ ns. There are 1,000 milliseconds in one second.
For example, 1 Millisecond (ms) = 0.0000167122996 Minute (Sidereal) (min (Sid)).

The millisecond is a unit of time equal to 10⁻³ seconds — one thousandth of a second.
1 ms = 0.001 s = 1,000 µs = 10⁶ ns. There are 1,000 milliseconds in one second.
To convert ms to seconds: divide by 1,000. To convert seconds to ms: multiply by 1,000.
Web page load times, video game frame timing (16.67 ms = 60 fps), network ping times, and heartbeat intervals (~800 ms).
Human reaction time to visual stimuli is about 250 ms. A housefly's wing beats once every 4 ms. A humming bird's wing: ~12 ms per beat.
Confusing ms (milliseconds) with Mb/s (megabits per second). In networking, ms measures latency while Mb/s measures throughput.
Your eye blink = ~300 ms. A 60 fps game = 16.67 ms per frame. These are great millisecond benchmarks.
The sidereal minute is 1/60 of a sidereal hour — approximately 59.836 seconds in solar time.
1 sidereal minute = 59.836 solar seconds. 60 sidereal minutes = 1 sidereal hour.
To convert sidereal minutes to solar seconds: multiply by 59.836. To solar minutes: multiply by 0.99727.
Precise observation timing, transit event recording, and telescope tracking rate calibration.
A sidereal minute is about 0.164 seconds shorter than a solar minute — small but significant over an observing session.
Using solar minutes when sidereal minutes are required in astronomical calculations — the error accumulates over time.
Sidereal minutes/seconds are just slightly shorter than their solar counterparts. The ratio is always ~0.99727.
