Choose an input unit and an output unit to convert time. The calculation uses the scale factors shown below.

How to convert time units

Nanoseconds × 1e-9 ÷ 0.000001 = Microseconds. Factors are relative to seconds.

Multiply your input by its scale factor, then divide by the output unit’s factor. All factors below are expressed in seconds per one unit. Some factors have been rounded to the precision shown.

Days mean 24 hours and weeks mean seven days. A Julian year is exactly 365.25 days here, not a calendar-year date calculation.
