Refresh Rate Frame Time Calculator

Summary

Enter a refresh rate in Hz or a frame time in ms and get the other value instantly, plus a table of common rates.

How it works

1. Pick a direction: Hz to ms, or ms to Hz.
2. Type the refresh rate (Hz) or frame time (ms) into the input.
3. The result updates live as you type, rounded to useful precision.
4. Check the reference table for common gaming and cinema refresh rates.
5. Click any row in the table to load that value into the calculator.

Use cases

• Compare how much faster 144Hz is than 60Hz in per-frame terms.
• Estimate input latency contribution from a monitor's refresh rate.
• Convert a target frame time budget (e.g. 6.94ms) back to a Hz spec.
• Check whether a game's frame time graph matches the monitor's native rate.
• Explain to a friend why 240Hz monitors show frames roughly every 4ms.
• Verify capture/recording frame timing against a target refresh rate.
