Why frame time tells you more than average FPS
Average FPS is useful, but it can hide uneven frame delivery. Two runs can report almost the same average frame rate while feeling very different if one contains long frame-time spikes. Frame time measures how long each individual frame takes to present, so consistent values usually produce smoother motion than a graph that jumps between fast and slow frames.
Use this converter when a benchmark quote only gives one side of the pair — for example “16.7 ms” without FPS, or “average 90 FPS” when you want the matching millisecond budget.
How to read common targets
A perfectly paced 60 FPS output corresponds to about 16.67 ms per frame. 120 FPS is ~8.33 ms, and 144 FPS is ~6.94 ms. Real captures fluctuate; consistency around the target matters more than every frame being identical.
A single 33 ms frame during a 144 FPS capture is a serious hitch, while the same 33 ms frame during a locked 30 FPS cutscene is expected. Always interpret spikes relative to the refresh or FPS cap you are aiming for.
Comparing 1% lows without mixing methods
Different tools define “1% low” differently — some use percentile frame times, others average a slowest subset of frames. Convert units with this page, but only compare lows that were calculated with the same method whenever possible.

Frequently Asked Questions
Is frame time better than FPS?
They describe the same rendering process from different angles. FPS is easier to summarize; frame time makes individual slow frames and uneven delivery much easier to see.
What is a good frame time for 60 FPS?
About 16.67 ms per frame when pacing is perfect. Healthy gameplay usually stays near that value without frequent jumps toward 20–33 ms.
Why do two tools show different 1% lows?
Calculation methods differ. Always compare results produced with the same analyzer and the same units (FPS vs milliseconds).
