How It Works
Pick Your Unit or Preset
Choose your home unit using the dropdown or load a one-click preset. Defaults are sensible engineering values so you can start right away.
Enter a Value
Type a number — conversion runs as you type. Many tools have multiple input boxes (W & H, size & speed) — edit any of them and the rest recompute.
Read Every Equivalent
Below the main result, the All Units / Summary panel shows your value across every supported unit, with engineering context (FPS, ping, EM band, etc.) where relevant.
Latency Converter Features
FPS Equivalent
Latency = 1 / frequency. 16.67 ms = 60 FPS, 8.33 ms = 120 FPS, 4.17 ms = 240 FPS. Useful for monitor refresh rate planning.
Frequency
Auto-switches to GHz / MHz / kHz / Hz based on the value. 1 ns = 1 GHz CPU clock; 1 μs = 1 MHz; 1 ms = 1 kHz.
Live Context
Smart label tells you whether the latency is gaming-tier, networking ping range, audio territory, or RAM/cache scale.
Ping Reference
<30 ms great, <100 ms good, <200 ms playable, >300 ms problematic for fast-paced games.

Frequently Asked Questions
1000 / 60 = 16.67 ms per frame. 120 FPS = 8.33 ms. 240 FPS = 4.17 ms. Esports players target sub-8 ms total system latency (input + render + display).
<30 ms = competitive. 30–60 ms = casual gaming feels great. 60–100 ms = playable for most games. >100 ms = noticeable lag. >300 ms = hard to play fast-paced games.
Pro audio targets <10 ms total round trip; live monitoring <5 ms. Bluetooth audio is typically 100–300 ms (too high for music games). USB audio is 1–5 ms.
L1 cache ~1 ns. L2 cache ~3 ns. L3 cache ~10–20 ns. Main RAM ~50–100 ns. SSD ~100,000 ns (100 μs). HDD ~10,000,000 ns (10 ms). The latency hierarchy spans 7 orders of magnitude.
Ping is one type of latency — round-trip network time. Latency more broadly means any delay: input lag, render lag, audio lag, storage seek time. Ping = latency in the network layer.
