Day (d). A day is 24 hours (86,400 seconds).
Nanosecond (ns). A nanosecond is one billionth of a second — light travels about 30 cm in that time.
There are 86,400,000,000,000 nanoseconds in one day.
Multiply the number of days by 86,400,000,000,000. For example, 10 days equal 864,000,000,000,000 nanoseconds.
One nanosecond equals 1.15741 × 10⁻¹⁴ days.
1.0368 × 10¹⁵ nanoseconds. Other common values: 5 days = 432,000,000,000,000 nanoseconds and 100 days = 8.64 × 10¹⁵ nanoseconds.
