FPS & Frame Time Calculator

Convert between frames per second and milliseconds per frame.

Convert a frame rate (FPS) into frame time in milliseconds, or the other way around. Frame time is simply 1000 divided by the frame rate, and understanding it helps explain why the jump from 30 to 60 FPS feels much bigger than 120 to 144 FPS.

Frequently Asked Questions

Why does going from 30 to 60 FPS feel like such a big jump?

Frame time drops from about 33ms to 16ms — a 17ms reduction — while 120 to 144 FPS only saves about 1.4ms, which is why higher frame rate gains feel smaller past a certain point.

What frame rate should I aim for?

It depends on your hardware and the game, but competitive players often prioritize a stable, high frame rate over other graphical settings.
