SwitchExplanation
QHD (2560x1440 / 1440p) is 2560x1440 (3.6864 MP), while 5K2K (5120x2160) is 5120x2160 (11.0592 MP). The conversion factor is 3686400/11059200 = 0.333333333333.
For QHD (2560x1440 / 1440p) to 5K2K (5120x2160), every result follows the same pixel-count mapping derived from the two listed resolution grids.
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 do I reverse QHD (2560x1440 / 1440p) to 5K2K (5120x2160)?
Use the mirror 5K2K (5120x2160) to QHD (2560x1440 / 1440p) 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.
