Explanation

nHD (640x360) is 640x360 (0.2304 MP), while 4K UHD (3840x2160) is 3840x2160 (8.2944 MP). The conversion factor is 230400/8294400 = 0.0277777777778.

From nHD (640x360) 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.

Method & Pixel Basis

  • Method basis: exact width × height definitions for both resolution grids shown in Direct Answer.
  • Applied mapping: pixel-count ratio between nHD (640x360) and 4K UHD (3840x2160).
  • Consistency rule: direct answer, calculator, and common values table use the same pixel totals and rounding policy.

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.

What is the opposite direction for nHD (640x360) to 4K UHD (3840x2160)?

Use the mirror 4K UHD (3840x2160) to nHD (640x360) 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.
