How to Convert Shake to Day (Sidereal)
To convert shakes to seconds: multiply by 10⁻⁸. To nanoseconds: multiply by 10.
1 shake = 10 ns = 10⁻⁸ s = 10,000 ps. A nuclear fission event takes about 1 shake.
For example, 1 Shake (shake) = 1.160576e-13 Day (Sidereal) (d (Sid)).

About Shake (shake)
Definition
A shake is an informal unit of time equal to 10 nanoseconds (10⁻⁸ seconds), used in nuclear physics.
Mathematical Relationship
1 shake = 10 ns = 10⁻⁸ s = 10,000 ps. A nuclear fission event takes about 1 shake.
Conversion Formula
To convert shakes to seconds: multiply by 10⁻⁸. To nanoseconds: multiply by 10.
Practical Applications
Timing nuclear chain reactions, modeling neutron transport in reactors, and nuclear weapon physics calculations.
Interesting Facts
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.
Common Mistakes
Not recognizing 'shake' as a real unit. It's informal but precisely defined and still used in nuclear engineering.
Educational Tips
A 'shake' = 10 nanoseconds. It was invented at Los Alamos to make nuclear timing calculations easier — humor in extreme circumstances.
About Day (Sidereal) (d (Sid))
Definition
The sidereal day is the time for Earth to rotate once relative to distant stars — approximately 23 hours, 56 minutes, and 4 seconds (86,164.0905 seconds).
Mathematical Relationship
1 sidereal day ≈ 23 h 56 min 4.09 s = 86,164.09 s. About 3 min 56 s shorter than a solar day.
Conversion Formula
To convert sidereal days to solar days: multiply by 0.99727. To hours: multiply by 23.9345.
Practical Applications
Telescope pointing and tracking, satellite ground track calculations, and astronomical observation scheduling.
Interesting Facts
Because of the ~4-minute difference, the night sky shifts gradually — the same star appears at the same position about 4 minutes earlier each night.
Common Mistakes
Equating sidereal day with solar day. The ~4-minute difference accumulates — after 6 months, sidereal noon is at solar midnight.
Educational Tips
Imagine Earth spinning AND orbiting: after one full spin (sidereal day), Earth has moved in its orbit, so the Sun hasn't quite returned to the same position — that takes ~4 more minutes.
