Convert FPS to frame time in milliseconds and back, with a refresh-rate table.
Updated July 10, 2026
How to use the monitor frame time calculator
- 1Enter a frame rate in FPS to get its frame time.
- 2Or enter a frame time in ms to get the equivalent FPS.
- 3Check the reference table for common refresh rates.
- 4Compare your target refresh rate's frame budget.
Common uses
- Understanding frame time versus FPS for smoothness
- Finding the frame budget for a target refresh rate
- Interpreting benchmark frame-time graphs
- Setting a frame-rate cap to match a monitor
Frequently asked questions
How do I convert FPS to frame time?
Frame time in milliseconds equals 1000 divided by the frame rate. So 60 FPS is 1000/60 = 16.67 ms per frame, 120 FPS is 8.33 ms, and 240 FPS is 4.17 ms. The two are just reciprocals, and this tool converts either direction.
Why does frame time matter more than average FPS?
Because smoothness depends on consistency. A steady 16.67 ms frame time feels smooth, but the same 60 FPS average with frequent spikes to 40 ms stutters visibly. That's why reviewers report frame time graphs and 1% lows — they reveal hitches that an average FPS number hides.
What frame time do I need for my monitor?
Each frame must finish inside the refresh interval. A 60 Hz monitor gives a 16.67 ms budget, 144 Hz gives 6.94 ms, and 240 Hz gives 4.17 ms. Miss the budget and a frame is dropped or repeated, which shows as stutter or tearing without a variable-refresh display.
About this tool
The monitor frame time calculator converts between frame rate and frame time — the number that actually governs smoothness. Frame time in milliseconds is 1000 divided by FPS, so 60 FPS is 16.67 ms, 144 FPS is 6.94 ms, and 240 FPS is 4.17 ms. Enter either value to get the other, and see a reference table of common refresh rates and their frame budgets. To display a refresh rate without dropped frames, your system has to finish every frame inside that budget. It's a pure calculation that runs entirely in your browser.
