1 day (d) = 86,400,000,000,000 nanoseconds (ns). To convert, multiply by 86,400,000,000,000: ns = d × 86,400,000,000,000. For example, 5 d = 432,000,000,000,000 ns.
ns = d × 86,400,000,000,000

The two units
Day (d). 24 hours. Days with a leap second or a daylight-saving change are longer or shorter.
Nanosecond (ns). One billionth of a second, the scale of CPU cycles.
Because both units are defined in terms of the same base unit, the factor 86,400,000,000,000 is exact, not a rounded measurement.
