How to Convert Shake to Fortnight
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) = 8.267196e-15 Fortnight (fn).

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 Fortnight (fn)
Definition
A fortnight is a unit of time equal to 14 days, or two weeks (1,209,600 seconds).
Mathematical Relationship
1 fortnight = 14 d = 2 wk = 336 h = 1,209,600 s.
Conversion Formula
To convert fortnights to days: multiply by 14. To convert fortnights to weeks: multiply by 2.
Practical Applications
Fortnightly pay cycles (common in Australia and UK), rental payment periods, and magazine publication schedules.
Interesting Facts
In Australia, being paid 'fortnightly' is the most common pay cycle. The FFF system defines speed in furlongs per fortnight.
Common Mistakes
Americans may be unfamiliar with the term. In US English, 'two weeks' is the standard equivalent.
Educational Tips
Fortnight = fourteen nights. In countries where it's common, it's as natural as saying 'week' — just meaning two of them.
