Frequently asked questions

Does more precision make the measurement more accurate?

No. Display precision controls decimal places. It does not improve the original measurement or remove uncertainty in an approximate unit. Keep intermediate digits and round the final value to suit your task.

Can I use the result as a date or timestamp?

This is a duration conversion. It does not choose a start date, account for time zones, or interpret a Unix timestamp. Keep the original unit and any calendar assumptions with your result.
