Detailed explanation-1: -25 megabytes in gigabytes is 0.025 GB, but when megabyte (MB) and mebibyte (MiB) are used interchangeably confusion arises.
Detailed explanation-2: -Depending on the aforementioned, a 30-second video could be anywhere from 1 to 30 megabytes. The 400 MB video file will download in less than 11 minutes over a.-25 Mb seconds. If the video is only 2 or 3 minutes long, you should be able to compress the file size significantly.
Detailed explanation-3: -One megabyte is about 1 million bytes (or about 1000 kilobytes). An MP3 audio file of a few minutes or a 10 million pixel image from a digital camera would typically take up few megabytes. The rule of thumb for MP3 audio is that 1 minute of audio takes up about 1 megabyte.
