Formula and method
1 h = 60 min = 3,600 s. These are elapsed durations. Converting a clock reading between time zones requires a date and time-zone rules instead. Enter a known value in the units shown; editing a result solves the conversion in reverse.
1 h = 60 min = 3,600 s
Worked example
Enter these known values and leave the other values blank.
- Hours
- 1 hrs
- Minutes

- Time
- 1:0:0 hrs / min / sec
Assumptions and limitations
- These are elapsed durations. Converting a clock reading between time zones requires a date and time-zone rules instead.
- The worked example uses the starting units. A unit selection preserves the quantity, so check the unit before entering a new number.

Which time convention does this conversion use?
These are elapsed durations. Converting a clock reading between time zones requires a date and time-zone rules instead.
How should I use a rounded result?
Keep enough digits for the accuracy of the original measurement. Display rounding changes the visible precision, while the calculation retains additional digits.
