To convert Planck times to seconds: multiply by 5.391 × 10⁻⁴⁴. To attoseconds: multiply by 5.391 × 10⁻²⁶.
tₚ ≈ 5.391 × 10⁻⁴⁴ s. It takes ~1.855 × 10⁴³ Planck times to make one second.
For example, 1 Planck Time (tₚ) = 4.457049e-50 Fortnight (fn).

The Planck time is the smallest meaningful unit of time in physics — approximately 5.391 × 10⁻⁴⁴ seconds.
tₚ ≈ 5.391 × 10⁻⁴⁴ s. It takes ~1.855 × 10⁴³ Planck times to make one second.
To convert Planck times to seconds: multiply by 5.391 × 10⁻⁴⁴. To attoseconds: multiply by 5.391 × 10⁻²⁶.
No practical applications — Planck time is purely theoretical. No conceivable technology could measure time intervals this short.
The age of the universe is about 8.08 × 10⁶⁰ Planck times. In the first Planck time after the Big Bang, all four fundamental forces may have been unified.
Thinking of Planck time as the 'shortest possible time' — it's the scale where our current physics breaks down, not necessarily a fundamental limit.
Planck time sets the scale where quantum mechanics and gravity intersect. Below this scale, we need a theory of quantum gravity we don't yet have.
A fortnight is a unit of time equal to 14 days, or two weeks (1,209,600 seconds).
1 fortnight = 14 d = 2 wk = 336 h = 1,209,600 s.
To convert fortnights to days: multiply by 14. To convert fortnights to weeks: multiply by 2.
Fortnightly pay cycles (common in Australia and UK), rental payment periods, and magazine publication schedules.
In Australia, being paid 'fortnightly' is the most common pay cycle. The FFF system defines speed in furlongs per fortnight.
Americans may be unfamiliar with the term. In US English, 'two weeks' is the standard equivalent.
Fortnight = fourteen nights. In countries where it's common, it's as natural as saying 'week' — just meaning two of them.
