Hour (h). An hour is 60 minutes (3,600 seconds).
Millisecond (ms). A millisecond is one thousandth of a second, used for reaction times and computer timing.
There are 3,600,000 milliseconds in one hour.
Multiply the number of hours by 3,600,000. For example, 10 hours equal 36,000,000 milliseconds.
One millisecond equals 2.77778 × 10⁻⁷ hours.
43,200,000 milliseconds. Other common values: 5 hours = 18,000,000 milliseconds and 100 hours = 360,000,000 milliseconds.
