How to Convert Femtoseconds to Picoseconds
To convert femtoseconds to picoseconds, multiply the time by the following conversion ratio: 0.001 picoseconds/femtosecond.
Since one femtosecond is equal to 0.001 picoseconds, you can use this simple formula to convert:
The time in picoseconds is equal to the time in femtoseconds multiplied by 0.001.
For example, here's how to convert 5 femtoseconds to picoseconds using the formula above.
How Many Picoseconds Are in a Femtosecond?
There are 0.001 picoseconds in a femtosecond, which is why we use this value in the formula above.
Our femtosecond to picosecond calculator automatically converts your time measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Femtoseconds and picoseconds are both units used to measure time. Keep reading to learn more about each unit.
What Is a Femtosecond?
A femtosecond is a unit of time equal to 1e-15 seconds (s), the base unit for time. One-quadrillionth of a second (10⁻¹⁵ s), used in ultrafast laser physics. [1]
The femtosecond is classified as a metric and SI-compatible unit of time. Femtoseconds can be abbreviated as fs; for example, 1 femtosecond can be written as 1 fs.
In the metric system, "femto" is the standard SI prefix for quadrillionths, or 10⁻¹⁵. This makes the femtosecond (fs) a convenient decimal multiple of the second (s).
In practice, femtoseconds (fs) are widely used across fine-tolerance laboratory, analytical, and micro-scale time measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Picosecond?
A picosecond is a unit of time equal to 1/1,000,000,000,000 of a second (1e-12 s). One-trillionth of a second (10⁻¹² s). [2]
The picosecond is classified as a metric and SI-compatible unit of time. Picoseconds can be abbreviated as ps; for example, 1 picosecond can be written as 1 ps.
In the metric system, "pico" is the standard SI prefix for trillionths, or 10⁻¹². This makes the picosecond (ps) a convenient decimal multiple of the second (s).
In practice, picoseconds (ps) are widely used across fine-tolerance laboratory, analytical, and micro-scale time measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting time between femtoseconds (fs) and picoseconds (ps), keep full floating-point precision (1 fs = 0.001 ps; 1 ps = 1,000 fs) during intermediate calculations and round only the final picosecond figure to match your instrument tolerance.
