About This Conversion
Milliseconds to seconds divides by 1,000, and is the conversion between how machines report timings and how people discuss them. Response times, frame times and animation durations are all measured in milliseconds.
A few anchors make the numbers meaningful: 16.67 ms is one frame at 60 fps, roughly 100 ms is the threshold below which an interface feels instant, and 200 ms is about human reaction time. A 2,000 ms page load is two seconds, which is already past the point where visitors start leaving.
