Refresh Rate ↔ Frame Time Converter

Refresh rate (Hz) and frame time (ms) describe the same thing from two angles. Enter a Hz value to see its exact frame time, or check the reference table for common rates.

Fixed math (frame time = 1000 ÷ Hz) — not a claim about any specific monitor.

Diminishing returns at higher refresh rates

The jump from 60Hz to 144Hz cuts frame time by about 9.7ms, but the jump from 240Hz to 360Hz only saves about 1.4ms — each step up matters less in absolute terms. Full monitor-matching criteria in our monitor buying guide.

Frequently Asked Questions

What's the exact formula used?

Frame time (ms) = 1000 ÷ refresh rate (Hz). It's a straightforward, fixed conversion — the same math applies whether you're converting your monitor's Hz setting or the FPS your game is actually rendering.

Is a higher refresh rate always worth it?

The gains shrink at higher numbers — 60Hz to 144Hz cuts frame time by about 9.7ms, while 240Hz to 360Hz only saves about 1.4ms. Whether that's worth the price premium depends on how sensitive you are to the difference and whether your GPU can sustain frame rates that high.
