The units
About these units
Days (d)
A day is 86,400 seconds. The Earth actually turns slightly faster or slower, so leap seconds are occasionally added to keep clocks in step.
Hours (h)
An hour is 60 minutes, or 3,600 seconds. Ancient Egyptians split day and night into 12 parts each, which is why we have 24.
