FPS to Hertz Calculator

This FPS to Hertz calculator helps you compare your game or video frame rate with your monitor’s refresh rate so you can understand how smooth your display will look. Frames per second (FPS) describes how many images your computer renders each second. Hertz (Hz) describes how many times your monitor can refresh the image each second. When these numbers line up, motion appears smoother and screen tearing is less likely.

The calculator also shows frame time in milliseconds, which is another way to think about performance. Lower frame time means each frame arrives faster. For example, 60 FPS equals about 16.67 ms per frame, while 144 FPS is about 6.94 ms. Seeing frame time makes it easier to compare settings and understand why a drop in FPS can feel stuttery even if the number still seems high.

Step-by-step

1. Enter the FPS your game or application is producing.
2. Enter your monitor’s refresh rate in Hz.
3. Review the calculated Hz and frame time results.
4. Read the guidance notes for suggestions like FPS caps or VRR.

This is useful for gamers tuning graphics settings, streamers balancing performance while live, and anyone comparing monitors. If your FPS is higher than your refresh rate, you may see tearing unless you use V‑Sync or variable refresh rate (G‑Sync/FreeSync). If your FPS is lower than your refresh rate, the display may repeat frames, which can feel less smooth. Matching a stable FPS to your monitor’s Hz usually delivers the best experience.

Real‑world examples include choosing whether to cap a game at 60, 120, or 144 FPS, or deciding if a 240 Hz display will benefit your setup. A competitive player might aim for a stable 144 FPS on a 144 Hz monitor, while a casual player might prefer higher visual settings at a consistent 60 FPS. The calculator helps you see the trade‑offs clearly.

Everything runs locally in your browser, so it is quick and private. Use it during performance tuning, hardware upgrades, or when shopping for a new display to understand how FPS, Hz, and frame time work together.

This calculator gives a quick reality check on frame times and how they relate to monitor refresh rates. Enter an FPS value and your display’s refresh to see the frame duration in milliseconds and whether you’re over, under, or matched. That’s useful for gamers tuning graphics settings, motion designers checking playback smoothness, and developers verifying timing budgets.

All calculations are client-side—no performance data is uploaded. The guidance text offers suggestions on whether to cap FPS, raise refresh, or lower quality settings depending on your ratio. When FPS exceeds refresh, you may see tearing without vsync or VRR; when FPS is below refresh, repeated frames can create judder. Matching or using variable refresh helps stabilize the experience.

Because the tool is lightweight, it works offline once loaded. Keep it alongside your system monitoring to understand what a 12 ms frame time means (about 83 FPS) or how close you are to fully using a 240 Hz display. It’s also handy for planning rendered exports for signage or installations where playback hardware has a fixed refresh rate.

Use it whenever you tweak settings, move between displays, or explain performance trade-offs to teammates or clients. Knowing the numbers makes it easier to balance fidelity and smoothness without guesswork.
