To convert ns to seconds: multiply by 10⁻⁹. To convert ns to microseconds: divide by 1,000.
1 ns = 10⁻⁹ s = 1,000 ps = 0.001 µs. Light travels about 30 cm (1 foot) in one nanosecond.
For example, 1 Nanosecond (ns) = 1.854858e+34 Planck Time (tₚ).

The nanosecond is a unit of time equal to 10⁻⁹ seconds — one billionth of a second.
1 ns = 10⁻⁹ s = 1,000 ps = 0.001 µs. Light travels about 30 cm (1 foot) in one nanosecond.
To convert ns to seconds: multiply by 10⁻⁹. To convert ns to microseconds: divide by 1,000.
CPU clock cycles (a 3 GHz processor has ~0.33 ns per cycle), DDR memory timing, Ethernet packet gaps, and GPS signal timing.
Grace Hopper handed out 30 cm wires to explain nanoseconds: 'This is one nanosecond' — the distance light travels in that time.
Confusing nanoseconds with milliseconds — they differ by a factor of 1,000,000. In computing, ns and ms are very different.
Grace Hopper's wire trick: hold a 30 cm ruler — light crosses it in 1 ns. This makes the abstract concept tangible.
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.
