How to Convert Picoseconds to Years
To convert picoseconds to years, multiply the time by the following conversion ratio: 3.168874e-20 years/picosecond.
Since one picosecond is equal to 3.168874e-20 years, you can use this simple formula to convert:
The time in years is equal to the time in picoseconds multiplied by 3.168874e-20.
For example, here's how to convert 5 picoseconds to years using the formula above.
How Many Years Are in a Picosecond?
There are 3.168874e-20 years in a picosecond, which is why we use this value in the formula above.

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). [1]
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.
What Is a Year?
A year is a unit of time equal to 31,556,952 seconds (s), the base unit for time. Average Gregorian calendar year (31,556,952 seconds). [2]
The year is classified as a standard unit of time. Years can be abbreviated as yr; for example, 1 year can be written as 1 yr.
When working with years (yr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, years (yr) are widely used across large-scale industrial, bulk, and macro-level time specifications within international standard workflows, engineering documentation, and technical data sheets.
When converting time between picoseconds (ps) and years (yr), keep full floating-point precision (1 ps = 3.168874e-20 yr; 1 yr = 3.155695e+19 ps) during intermediate calculations and round only the final year figure to match your instrument tolerance.
