Is 8 megapixels 4K?

No, 8 megapixels is not exactly the same as 4K, though the two are very close. Here's the explanation:

Resolution Comparison:

• 4K resolution refers to a display or video resolution of 3840 x 2160 pixels (UHD 4K), which equals approximately 8.3 megapixels.

  $$3840 \times 2160 = 8,294,400 \, \text{pixels} \approx 8.3 \, \text{megapixels}$$

• 8 megapixels is a resolution that corresponds to 3264 x 2448 pixels (in terms of camera sensor resolution, for example). This is just slightly less than the 4K resolution in terms of total pixels.

  $$3264 \times 2448 = 7,986,432 \, \text{pixels} \approx 8 \, \text{megapixels}$$

Key Differences:

• 8 Megapixels: Typically used for camera sensors, photos, and some lower-resolution video content.
• 4K: Refers to a specific display or video resolution of 3840 x 2160 (UHD) or 4096 x 2160 (DCI), which is slightly more than 8 megapixels.

Summary:

• 8 megapixels is very close to 4K (which is 8.3 megapixels), but not exactly the same. 4K refers to a resolution of 3840 x 2160 pixels, whereas 8 MP typically refers to 3264 x 2448 pixels. So, while they're similar in pixel count, 4K resolution is a bit higher than 8 MP resolution.
