To convert sidereal minutes to solar seconds: multiply by 59.836. To solar minutes: multiply by 0.99727.
1 sidereal minute = 59.836 solar seconds. 60 sidereal minutes = 1 sidereal hour.
For example, 1 Minute (Sidereal) (min (Sid)) = 5983617000 Shake (shake).

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.
A shake is an informal unit of time equal to 10 nanoseconds (10⁻⁸ seconds), used in nuclear physics.
1 shake = 10 ns = 10⁻⁸ s = 10,000 ps. A nuclear fission event takes about 1 shake.
To convert shakes to seconds: multiply by 10⁻⁸. To nanoseconds: multiply by 10.
Timing nuclear chain reactions, modeling neutron transport in reactors, and nuclear weapon physics calculations.
In a nuclear explosion, the chain reaction is complete in about 50–60 shakes (500–600 ns). The name reflects the era's dark humor.
Not recognizing 'shake' as a real unit. It's informal but precisely defined and still used in nuclear engineering.
A 'shake' = 10 nanoseconds. It was invented at Los Alamos to make nuclear timing calculations easier — humor in extreme circumstances.
