FPS Calculator

Enter target FPS to calculate frame time (ms) and frame interval.

Frame time 16.67 ms
Frames per second 60

Usage

Enter target FPS to get frame time in milliseconds. 60 FPS ≈ 16.67ms, 30 FPS ≈ 33.33ms. In Unity, use Time.deltaTime for elapsed time since last frame. Reverse lookup (frame time → required FPS) also available.

When to use

When setting target FPS for your game and need to know max processing time per frame. Useful for performance tuning and physics/animation timing.

Examples

60 FPS → 16.67ms/frame, 120 FPS → 8.33ms/frame, 30 FPS → 33.33ms/frame. VR often uses 90 FPS (≈11.1ms).

Tips

  • FPS beyond monitor refresh rate (60Hz/120Hz) won't be displayed.
  • Physics often uses fixed timestep (e.g. 50Hz), separate from render FPS.
  • At 16.67ms/frame, consider splitting heavy work across multiple frames.
