How to Convert Shake to Year (Tropical)
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) = 3.168877e-16 Year (Tropical) (yr (Trop)).

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 (Tropical) (yr (Trop))
Definition
The tropical year is the time for the Sun to return to the same equinox point — approximately 365.24219 days (31,556,925.216 seconds).
Mathematical Relationship
1 tropical year ≈ 365.24219 days ≈ 365 d 5 h 48 min 45 s. Shorter than the sidereal year by about 20 minutes due to precession.
Conversion Formula
To convert tropical years to days: multiply by 365.24219. To Julian years: multiply by 365.24219/365.25.
Practical Applications
Calendar design — the Gregorian calendar's average year (365.2425 days) approximates the tropical year to within 26 seconds.
Interesting Facts
The tropical year is slowly shortening — by about 0.53 seconds per century. In the year 1900, it was 365.24220 days.
Common Mistakes
Confusing tropical year with sidereal year — the tropical year is ~20 minutes shorter due to axial precession.
Educational Tips
The tropical year governs seasons. If we used the sidereal year for calendars, seasons would slowly drift through the months over ~26,000 years.
