How to Convert Attosecond to Planck Time
To convert as to seconds: multiply by 10⁻¹⁸. To convert as to femtoseconds: divide by 1,000.
1 as = 10⁻¹⁸ s = 0.001 fs. Light travels only about 0.3 nm (the width of a water molecule) in one attosecond.
For example, 1 Attosecond (as) = 1.854858e+25 Planck Time (tₚ).

About Attosecond (as)
Definition
The attosecond is a unit of time equal to 10⁻¹⁸ seconds — one quintillionth of a second.
Mathematical Relationship
1 as = 10⁻¹⁸ s = 0.001 fs. Light travels only about 0.3 nm (the width of a water molecule) in one attosecond.
Conversion Formula
To convert as to seconds: multiply by 10⁻¹⁸. To convert as to femtoseconds: divide by 1,000.
Practical Applications
No everyday applications yet. Research applications include tracking electron motion and developing future ultrafast electronics.
Interesting Facts
An attosecond is to one second as one second is to about 31.7 billion years — roughly twice the age of the universe.
Common Mistakes
Confusing 'as' (attosecond) with the English word 'as'. In scientific texts, context and formatting prevent ambiguity.
Educational Tips
The 2023 Nobel Prize in Physics was awarded for attosecond pulse generation — this field is at the frontier of ultrafast science.
About Planck Time (tₚ)
Definition
The Planck time is the smallest meaningful unit of time in physics — approximately 5.391 × 10⁻⁴⁴ seconds.
Mathematical Relationship
tₚ ≈ 5.391 × 10⁻⁴⁴ s. It takes ~1.855 × 10⁴³ Planck times to make one second.
Conversion Formula
To convert Planck times to seconds: multiply by 5.391 × 10⁻⁴⁴. To attoseconds: multiply by 5.391 × 10⁻²⁶.
Practical Applications
No practical applications — Planck time is purely theoretical. No conceivable technology could measure time intervals this short.
Interesting Facts
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.
Common Mistakes
Thinking of Planck time as the 'shortest possible time' — it's the scale where our current physics breaks down, not necessarily a fundamental limit.
Educational Tips
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.
