Attoseconds to exaseconds converter
Convert attoseconds (as) to exaseconds (Es). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in as; the result is in Es.
Formula
Worked example
Convert 1 as to Es:
1 as ≈ 1e-36 Es
Multiply your as value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What attoseconds measure
Attoseconds (as) represent time & duration. One unit equals 10^-18 s. The second is the SI base unit of elapsed time. Decimal prefixes change its scale.
Reading the result in exaseconds
Exaseconds (Es) represent time & duration. One unit equals 10^18 s. The second is the SI base unit of elapsed time. Decimal prefixes change its scale.
Where this conversion helps
Compare timing intervals, instrument response and elapsed process durations. An elapsed duration has no time zone. Calendar months and years do not have a fixed number of seconds.
How the scale changes
The input unit has a factor of 1e-18 s; the output unit has a factor of 1e18 s. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
