About This Tool
FPS tells you how many frames a game draws each second. Frame time is the opposite view: how many milliseconds each frame takes. Frame time reveals stutter that an average FPS number can hide.
Use this tool to convert between the two. For example, 60 FPS means a new frame every 16.67 ms, while 144 FPS means one every 6.94 ms. Lower frame time makes games feel more responsive.
How to Use
- Type your FPS to see its frame time.
- Or type a frame time in ms to see the FPS.
- Compare with the reference table for common targets.
- Aim for steady frame times, not just a high average.
Frequently Asked Questions
What is a good FPS for gaming?
60 FPS is smooth for most games. Competitive players often target 144 FPS or more on a matching high refresh rate monitor.
What is the formula?
Frame time in ms equals 1000 divided by FPS.
Why does stutter happen at high FPS?
Uneven frame times, background tasks or thermal throttling can cause spikes even when the average FPS looks high.
