SwitchExplanation
UW-FHD (2560x1080) is 2560x1080 (2.7648 MP), while 4K UHD (3840x2160) is 3840x2160 (8.2944 MP). The conversion factor is 2764800/8294400 = 0.333333333333.
From UW-FHD (2560x1080) to 4K UHD (3840x2160), the calculator uses one fixed pixel-count ratio based on the exact width × height definitions of both resolution formats.
Keep the same direction when comparing render load, export scale, or equivalent frame counts, because the reverse route applies the inverse pixel-count ratio.

Frequently Asked Questions
Does this conversion preserve aspect ratio?
Not necessarily. It compares total pixel counts only; aspect ratio may differ between the two formats.
How can I convert back from 4K UHD (3840x2160) to UW-FHD (2560x1080)?
Use the mirror 4K UHD (3840x2160) to UW-FHD (2560x1080) route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can this estimate performance impact?
It helps approximate pixel workload differences, but real performance also depends on GPU, game/app settings, and pipeline overhead.
