Forgive us Americans and being bad at metric. I personally wouldn’t have noticed the mistake, but I only have two brain cells.

For other dummies, it should be milliseconds (1000x difference)

According to Wikipedia:

> The duration of a blink is on average 100–150 milliseconds according to UCL researcher and between 100 and 400 ms according to the Harvard Database of Useful Biological Numbers.

https://en.wikipedia.org/wiki/Blinking

They have a link to a source for that claim... and the source says 300 to 400 milliseconds. So whoever wrote and edited the OP article just messed this up.

Maybe it was intended to mean the time between neurological impulse to blink and the physical eyelid moving? Still, yeah, original text seems misleading.

The 100-200 milliseconds duration of a blink was often cited in web development circles in the late 90s / early '00s, that I sometimes forget it isn't a widely known fact.
