FPS & Frame Time Calculator
Choose a conversion and enter a value to calculate the equivalent performance target.
Formula
Frame Time = 1000 ÷ FPS
Result
16.67ms
Calculation
1000 ÷ 60 = 16.67 ms
Common FPS & Frame Time Values
Select a common FPS target to calculate its frame time.
How to Calculate FPS and Frame Time
FPS and frame time describe the same rendering performance from two different perspectives. FPS measures how many frames are rendered each second, while frame time measures how long it takes to render a single frame.
Enter FPS
Enter the target or measured frames per second. For example, a game running at 60 FPS renders approximately 60 frames every second.
Apply the Formula
The calculator divides 1000 milliseconds by the FPS value to determine the amount of time available to render each frame.
Read Frame Time
The result shows the maximum frame time available at that FPS target. For example, 60 FPS corresponds to approximately 16.67 milliseconds per frame.
FPS ↔ Frame Time Formula
Frame Time = 1000 ÷ FPS
FPS = 1000 ÷ Frame Time
Example: At 120 FPS, each frame has approximately 8.33 milliseconds of rendering time available.
Frequently Asked Questions
What is frame time?
Frame time is the amount of time required to render one frame, usually measured in milliseconds. For example, 60 FPS corresponds to approximately 16.67 milliseconds per frame.
How do you calculate frame time from FPS?
Frame time is calculated by dividing 1000 milliseconds by the FPS value. For example, 1000 ÷ 60 = 16.67 milliseconds per frame.
How do you calculate FPS from frame time?
FPS is calculated by dividing 1000 milliseconds by the frame time. For example, 1000 ÷ 8.33 ≈ 120 FPS.
What is the frame time for 60 FPS?
60 FPS corresponds to approximately 16.67 milliseconds per frame.
What is the frame time for 120 FPS?
120 FPS corresponds to approximately 8.33 milliseconds per frame.
Does lower frame time mean better performance?
A lower frame time means each frame is being produced more quickly. Higher FPS therefore corresponds to lower frame time, although overall game performance also depends on factors such as CPU workload, GPU workload and frame-time consistency.
