The basic unit of Internet Time is the beat, 1/1000 of a day.
This is what you'd get if you divided a day into 10 decimal-hours and then divided each decimal hour into 100 decimal-minutes.
But, Swatch didn't call them decimal-hours and decimal-minutes. They called them beats. So what do you call 0.1 (1/10) beat? And what do you call 100 beats?
This page shows what happens if you apply standard metric prefixes.
For information on how I got this information, see the links at the bottom of the page.
