Frequently asked questions

Are gallons, quarts, pints, cups, and fluid ounces US units?
Yes. The volume conversions use US customary values, not Imperial UK measures.
How are months and years converted to time?
They are averages: one month is 2,629,800 seconds and one year is 31,557,600 seconds. Use a date-duration calculator for calendar-specific intervals.
Can I edit either side of the conversion?
Yes. Entering a value in either field recalculates the other field using the selected unit pair.
