Monitor Refresh Rate (60Hz vs 144Hz vs 240Hz vs 360Hz) Frame Time Calculator
Convert monitor refresh rate (Hz) and game FPS into exact frame time in milliseconds (ms) and input lag savings.
Reviewed by: Lucas 'Vortex' Chen • Pro Esports Hardware & Engine Telemetry Lab
Methodology: Verified Formula
Presets:
Frame Interval at 240Hz
4.17 ms per frame
Latency Reduction vs 60Hz
-12.50 ms (75% faster)
Frames Displayed per Second
240 FPS Cap Recommended: 237 FPS (G-Sync/FreeSync)
Capping FPS 3 frames below max Hz prevents V-Sync input lag.

Mathematical Formula & Step-by-Step Guide
Primary mathematical equation used by this model:
Frame Time (ms) = 1,000 / Refresh Rate (Hz)
- Configure your primary input (Target Monitor Refresh Rate (Hz), baseline set to 240) using either the direct numeric box or synchronized range slider.
- Adjust the remaining parameters (Current Monitor Refresh Rate (Hz)) to mirror your exact scenario.
- Examine the primary output alongside the secondary breakdown metrics and the 6-tier benchmark comparison table below.

Frequently Asked Questions — Hz to Frame Time (ms)
What mathematical formula does the Monitor Refresh Rate (60Hz vs 144Hz vs 240Hz vs 360Hz) Frame Time Calculator use?
This calculator implements the verified relationship: Frame Time (ms) = 1,000 / Refresh Rate (Hz). Each variable (Target Monitor Refresh Rate (Hz), Current Monitor Refresh Rate (Hz)) is evaluated in real time using double-precision floating-point arithmetic so there is zero rounding drift across multi-step scenarios.
How does changing Target Monitor Refresh Rate (Hz) impact the final result?
Target Monitor Refresh Rate (Hz) acts as the primary driver in this model (default baseline: 240). Use the Reference Benchmark Table on this page to compare how scaling Target Monitor Refresh Rate (Hz) from conservative to aggressive levels changes both the primary outcome and secondary ratios.
What standards and sources back this Hz to Frame Time (ms) methodology?
Our model is audited by Lucas 'Vortex' Chen • Pro Esports Hardware & Engine Telemetry Lab and calibrated against Valve Source 2 (CS2 m_yaw 0.022°), Riot Games Valorant Engine (0.07° yaw), Respawn Apex Engine, USB HID 1000Hz–8000Hz Polling Specifications & VESA DisplayHDR/Refresh Standards. Note: In-game sensitivity conversions preserve 1:1 physical 360° turn circumference at matching field-of-view (FOV) settings.
