FPS & Frame Time

Convert frame rate to milliseconds. Results are estimates and run privately in your browser.

Try a worked example

Illustrative inputs, not actual studio results. Selecting an example replaces the values below; edit them to use your own numbers.

60 frames per second leaves about 16.67 milliseconds per frame. This is a frame budget, not measured device performance.

30 frames per second leaves about 33.33 milliseconds per frame. The interval doubles; this does not mean input latency is exactly 33.33 ms.

How to use this tool

Enter the frame-rate target or a measured FPS value. For diagnosis, obtain measurements on the device that actually runs the game instead of relying only on an editor preview.

How the calculation works

Frame time in milliseconds = 1,000 ÷ frames per second

Example

At 60 FPS, each frame has approximately 16.67 milliseconds to render.

Read the result without overestimating it

At 60 FPS the budget is about 16.67 ms. A 25 ms frame misses that target even if nearby frames are fast. This conversion is a budget reference, not a profiler or a measurement of input delay.

Why this result matters

Frame time is often more useful than FPS when profiling. A small increase in milliseconds can cause a visible frame-rate drop once the frame budget is exceeded.

Tips for a more useful estimate

  • Profile on the actual target device.
  • Watch spikes, not only the average.
  • Measure CPU and GPU time separately when possible.

Frequently asked questions

What is the budget for 30 FPS?

Approximately 33.33 milliseconds per frame.

Does a 120 Hz screen guarantee 120 FPS?

No. The device and game must also render frames fast enough.
