About Day
One day is 24 hours or 86,400 seconds (civil day, no leap-second adjustment in this tool).
About Nanosecond
One nanosecond is one billionth of a second. CPU timings and optics may reference nanoseconds.
How to convert days to nanoseconds
1 day is equal to 8.64000000e+13 nanosecond:
1 d = (86400 s ÷ 1e-9 s) ns = 8.64000000e+13 ns
Each day is defined as 86400 s and each nanosecond as 1e-9 s, so one d equals 86400 ÷ 1e-9 ns = 8.64000000e+13 ns.
Let t(d) be the numeric value of the same duration measured in Day (d), and t(ns) the value in Nanosecond (ns). Then:
t(ns) = t(d) × (86400 / 1e-9)
Equivalently, divide by how many d fit into one ns (seconds per ns divided by seconds per d):
t(ns) = t(d) ÷ 1.15740741e-14
Or: nanosecond = day ÷ 1.15740741e-14
Examples
Example #1: Convert 20 d to nanosecond
20 d = 20 d × (86400/1e-9) ns = 1728000000000000 ns
20 d = 20 d ÷ 1.15740741e-14 = 1728000000000000 ns
Example #2: Convert 50 d to nanosecond
50 d = 50 d × (86400/1e-9) ns = 4320000000000000 ns
50 d = 50 d ÷ 1.15740741e-14 = 4320000000000000 ns
Summary
To convert Day to Nanosecond, multiply the value in d by the ratio of seconds per d divided by seconds per ns. Equivalently: value_ns = value_d × (86400 / 1e-9). Numerically, 1 d equals 86400000000000 ns.
Relationship context
You are converting between longer spans (days to years, with average month/year definitions) (Days) and subsecond precision (milliseconds and smaller) (Nanoseconds). Very large and very small steps share the same second-based definitions here. The numeric factor is 8.640000e+13.
