The formula
s = ms × 0.001
Worked through with a real value: 10 milliseconds = 0.01 seconds.
Going the other way: ms = s × 1000, so 1 second = 1000 milliseconds.
What each unit is
- millisecond ms
- A thousandth of a second, the standard unit for measuring latency in computing and communications.
- second s
- The SI base unit of time, defined since 1967 as 9,192,631,770 cycles of cesium-133 radiation.
Where these come from
- 1 millisecond = 0.001 seconds
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
