How to Convert Shake to Year (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) = 3.168754e-16 Year (Sidereal) (yr (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 Year (Sidereal) (yr (Sid))
Definition
The sidereal year is the time for Earth to complete one orbit relative to the fixed stars — approximately 365.25636 days (31,558,149.7632 seconds).
Mathematical Relationship
1 sidereal year ≈ 365.25636 days ≈ 365 d 6 h 9 min 10 s. About 20 min 24 s longer than the tropical year.
Conversion Formula
To convert sidereal years to days: multiply by 365.25636. To tropical years: multiply by 365.25636/365.24219.
Practical Applications
Tracking stellar positions, calculating satellite orbital decay, and determining long-term star catalog corrections.
Interesting Facts
The ~20-minute difference between sidereal and tropical years is caused by axial precession — Earth's axis traces a full circle every ~25,772 years.
Common Mistakes
Using sidereal year when tropical year is intended (or vice versa) in calendar calculations.
Educational Tips
Think of it this way: the sidereal year measures Earth's orbit relative to stars. The tropical year measures relative to seasons. Precession makes them differ.
