Frequently asked questions
Does this converter treat months and years as fixed durations?
No. It converts only fixed durations from seconds through seven-day weeks. Calendar months and years vary in length and are intentionally not guessed.
Are the results rounded?
The calculation retains full JavaScript number precision; the precision control only formats the displayed result.
