How to Convert Second to Attosecond
To convert seconds to minutes: divide by 60. To convert to hours: divide by 3,600. To milliseconds: multiply by 1,000.
1 s = 1,000 ms = 10⁶ µs = 10⁹ ns. There are 60 seconds in a minute and 86,400 in a day.
For example, 1 Second (s) = 1.000000e+18 Attosecond (as).

| 50 | 5.000000e+19 |
| 100 | 1.000000e+20 |
| 500 | 5.000000e+20 |
| 1000 | 1.000000e+21 |
About Second (s)
Definition
The second is the SI base unit of time, defined by the fixed value of the cesium-133 hyperfine transition frequency: exactly 9,192,631,770 cycles.
Mathematical Relationship
1 s = 1,000 ms = 10⁶ µs = 10⁹ ns. There are 60 seconds in a minute and 86,400 in a day.
Conversion Formula
To convert seconds to minutes: divide by 60. To convert to hours: divide by 3,600. To milliseconds: multiply by 1,000.
Practical Applications
All timekeeping — clocks, timers, stopwatches, cooking, traffic lights, music tempo (BPM), and heartbeat monitoring.
Interesting Facts
Cesium atomic clocks are accurate to about 1 second in 300 million years. The 2019 SI redefinition preserved the second's cesium-based definition.
Common Mistakes
Using 'sec' instead of 's' in scientific writing. Also, assuming all seconds are exactly equal — leap seconds exist to correct for Earth's slowing rotation.
Educational Tips
A heartbeat lasts about 0.8 seconds. Counting 'one Mississippi' is a classic way to estimate one second.
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.
