2005年3月4日 · What are kilobytes, megabytes, and gigabytes? Answer: The size of computer data is measured in bytes. Just like a kilometer is a measure of 1000 meters, kilobytes, megabytes, and gigabytes are larger measurements of bytes.

2018年1月31日 · MB vs KB is like pounds vs. ounces, they are just different units of the same thing. Don't worry about that, just be concerned with the resolution, that's what determines your printability. Also, don't expect any professional or even …

2019年1月9日 · But 540 KB is 0.540/4.1 = 13% of the 4.1 MB original size. It might be 29% of previous JPG size, but it is 13% of original uncompressed size. So that is 1/8 of original uncompressed size, which is usually considered "decent" quality. Not optimum, not maximum quality, but generally decent, perhaps good enough for some uses.

Greater KB — bigger files — means more data, but doesn't necessarily mean more information. A file with a lot of sharp detail will be bigger than a blurry one, but also a file with lots of noise will be bigger than a clean one.

2003年11月13日 · Which is faster – Kbps or Mbps? Answer: Kbps stands for "kilobits per second," while Mbps stands for "megabits per second."

2010年7月16日 · There are some general rules you can use to determine the "maximum" (I use that term loosely) print size. Keep in mind that the quality of a print is often more dependent on what is being printed than its size in megapixels, and even if your image size is not dense enough to mathematically fit onto a certain page size, you can still blow most images up pretty large …

2017年11月19日 · And, of course, including a thumbnail in the image file will also increase its size by a few kB. The "DCT method" is an obscure setting that basically controls the way the rounding and frequency component separation calculations are done: it does have a slight but noticeable effect on both image quality and size, but it can go either way.

2002年6月7日 · Why are there 1024 bytes in a kilobyte? Answer: Many people think that there are 1000 bytes in a kilobyte. After all, "kilo" means 1000.

4*6*(300^2)*20 = 43200000 bits = 5400 KB = 5.4 MB. Okay, so, you're right in the multiplication here (give or take a quibble about binary vs. decimal KB and MB). That is the uncompressed byte size of the data which makes up the image.

2012年12月5日 · As a final experiment, I copied the 9.1 Mb post-processed file and the TIFF file resulting from it both to JPEG files with maximum quality setting. Both resulting JPEG files are exactly the same size to the byte of about 8.5 Mb. This shows that even at maximum quality, just a little lossy compression is going on, but not much.
