Milliseconds to nanoseconds – convert ms to ns

Convert milliseconds to nanoseconds (ms to ns) to zoom from human-scale timing down to hardware-level precision. Great for latency analysis, profiling and explaining performance numbers.

Open the interactive ms → ns converter:

Use main converter (ms → ns) or switch to ns → ms

The time converter also links nanoseconds, microseconds, seconds, minutes, hours and days using exact decimal factors.

Quick reference: ms to ns

One millisecond equals 1,000,000 nanoseconds. So: ns = ms × 1,000,000. Example conversions:

Milliseconds (ms) Nanoseconds (ns)
0.001 ms1,000 ns
0.01 ms10,000 ns
0.1 ms100,000 ns
1 ms1,000,000 ns
5 ms5,000,000 ns
10 ms10,000,000 ns
100 ms100,000,000 ns
