Understanding days
A day here is a fixed duration of 24 hours. A local calendar day across a daylight-saving transition can have a different elapsed length; use a date/time tool for that task.
Understanding weeks
A week here is seven fixed 24-hour days, or 168 hours. Weeks cannot be turned into calendar months with one exact constant because month lengths vary.
Precision and rounding
The calculator keeps decimal precision during the conversion. Displayed values use up to 10 significant digits; an approximation sign marks the reference results. Keep extra digits until your final measurement or purchase decision.
