Working calculators for FPS, ping conversion, game download time, refresh rate, resolution scaling, and PPI — essential for PC gamers.
Optimising your gaming setup requires understanding key performance metrics. Our free gaming calculators help you measure FPS, latency, download times, and display specifications — all instantly and locally in your browser.
Frames Per Second (FPS) measures how smoothly a game runs. Higher FPS means smoother gameplay and better responsiveness. 60 FPS is the standard for smooth gameplay, while competitive gamers often target 144 FPS or higher. Our FPS calculator converts frames per second to frame time (measured in milliseconds) — lower frame time means less input lag. For example, 60 FPS equals 16.67ms frame time, while 144 FPS equals just 6.94ms.
Ping (measured in milliseconds) is the time it takes for data to travel from your PC to the game server and back. Lower ping means less lag and more responsive gameplay. Under 20ms is excellent, 20-50ms is good, 50-100ms is playable, and over 150ms is noticeable lag. Our ping converter shows you exactly how many seconds of delay you're experiencing.
Modern games can be 50-150 GB or more. Knowing how long downloads will take helps you plan. Our download time calculator estimates download duration based on file size and internet speed. For example, a 100 GB game at 100 Mbps takes approximately 2 hours and 13 minutes. Use this to decide when to start large downloads.
Refresh rate (measured in Hz) determines how many times per second your monitor updates the image. A 144Hz monitor updates every 6.94ms, while 60Hz updates every 16.67ms — higher refresh rates provide smoother motion and less blur. Our refresh rate calculator converts Hz to milliseconds per frame.
Resolution scaling helps you understand how different resolution settings affect performance. For example, 75% scaling of 1920×1080 (1080p) results in 1440×1080. Our PPI (Pixels Per Inch) calculator tells you how sharp your display is — higher PPI means sharper text and images.
