About Converting Yoctoseconds to Attoseconds
Yoctosecond and Attosecond are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Specifically: Yoctosecond is 1e-24 second units, and attosecond is 1e-18 second units.
Formula
attoseconds = yoctoseconds × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctosecond equals 1e-24 base units, and 1 attosecond equals 1e-18 base units, so dividing one by the other gives the direct yoctosecond-to-attosecond factor of 0.000001.
Simple example
1 ys × 0.000001 = 0.000001 as
1 yoctosecond = 0.000001 attoseconds.
Real-world example
24 ys × 0.000001 = 0.000024 as
24 yoctoseconds = 0.000024 attoseconds.

Reverse conversion: Attosecond to Yoctosecond
0.000001 as × 1000000 = 1 ys
0.000001 attoseconds = 1 yoctoseconds.
yoctoseconds = attoseconds × 1000000

Frequently asked questions
How many attoseconds are in 1 yoctosecond?
1 yoctosecond equals 0.000001 attoseconds, using the exact defined conversion factor rather than an estimate.
How do I convert yoctosecond to attosecond?
Multiply the yoctosecond value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert attosecond back to yoctosecond?
Use the reverse factor: 1 attosecond equals 1,000,000 yoctoseconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a yoctosecond?
Yoctosecond (ys) is a unit of time.
What is a attosecond?
Attosecond (as) is a unit of time.
Is the yoctosecond to attosecond conversion exact?
Yes. Both yoctosecond and attosecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
