Time units
Time converts cleanly for fixed units — 60 seconds in a minute, 3,600 in an hour, 86,400 in a day. Months and years are trickier because they vary, so this converter uses average lengths (about 30.44 days per month and 365.25 days per year) for those, which is standard for general conversions.
