What is a millisecond?

The computing and networking time unit — 0.001 second

Definition

The millisecond equals 0.001 second. Essential in computing, networking and high-speed photography. Human reaction time is about 200–300 ms. Video frame rates of 60 fps correspond to a 16.67 ms per frame.

Common uses

  • Network latency and ping times
  • Game frame rates and rendering
  • Human reaction time studies

🌍 Real-world scale

Ping to a local server: 5–20 ms. Game frame at 60 fps: 16.67 ms. Human reaction: 200–300 ms.

Tips

  • 1 ms = 0.001 s = 1000 µs.
  • 60 fps = 16.67 ms/frame; 144 Hz gaming monitor = 6.94 ms/frame.
  • Network latency under 30 ms feels instantaneous to humans.

Common mistakes

  • Reading ms as s on game latency — 100 ms vs 100 s would be drastically different.
  • Confusing ms with µs (microsecond, 1000× smaller).
  • Treating ms as a generic "short time" — it is specifically 10⁻³ s.
