1 mb=1 minute of film.
So 2 hours would be 120 Megabytes.
It depends of the type of the file and the quality. In a regular divx (avi) format a movie of 1h30 will take around 800 MB, so in 58 GB you could store more or less 72 movies.
If you are referring to Giga Bytes in a mega bit (Bytes are different to bits - 8 bits makes a byte) and the m to M (meaning mega) 70/8 = 8.75 so 70Mb = 8.75MB 1024MB=1GB so then 8.75/1024 or 0.00854492188 GB in 70 Mb, but if you were referring mb to MB (mega byte) then simply 70/1024 = 0.068359375 GB are in 70 MB. The capitals are important - so make sure you get them right or say the long name.
What, an individual .MP3 song? Depends on two things - the length of the song and the bit rate that the track was ripped at. Obviously ripping a 1 minute song creates a smaller .MP3 file than a 3 minute song at the same bit rate. On the other hand, a 1 minute song at 192kb could be a bigger file than a 3 minute song at 64kb. Higher the bit rate, the better quality the .MP3 will be.
If you are talking 'memory' in computers than I think you want to say how many MB in a GB? 1,000 MB = 1 GB
1 Mb = 1024 Kb
About 500 Mb in reasonable quality video.
That can vary a LOT, depending on the video's size (height and width, in pixels), as well as its quality.
There is no set standard. Movie sizes will vary greatly on the quality of the video. The higher the quality the higher the size. Movies can range from 300Mb to 7+Gbs in size depending on a variety of factors.
Depends - 2054 megabytes of what? - 1 minute of MP3 music in a fairly high quality takes about 1 MB, but the amount of MB/minute can really vary a lot. A minute of a DVD-quality movie takes up much more space than that.
There is no standard conversion between minutes and megabytes. For a fairly high-quality MP3 file, you can estimate about one minute per megabyte. For low, but still acceptable, quality, you can get more. For instance, the German courses from Deutsche Welle have about 4-5 minutes for each megabyte. For even a low-quality movie you can expect several megabytes for every minute.
Please note that MB and GB are units of data storage, NOT of time. This question is usually relevant for audio and video files. It really depends a lot on whether it is music or video; and in both cases, on the quality. A typical MP3, in reasonably good quality, might take about 1 MB (note: 1 GB = 1024 MB) for every minute of audio; but it may also be several times more or less, depending on the quality. For movies, a DVD - which has a fairly high quality - uses 4.7 GB for a full movie (about 2 hours); Blu-Ray uses several times that amount (at an even higher quality). But movies are often ripped in a reduced quality (the quality still being quite acceptable), typically at around 200-400 MB per hour.
How many hours of what? A typical - fairly high-quality - MP3 needs about 1 MB per minute, that would give you perhaps 17 hours of music in one GB. It is possible to save sound in about 1/5 of this space, and still have a decent (though not excellent) quality; that would give you 85 hours of sound in 1 GB. Ogg Vorbis uses less space (or offers a higher quality for the same amount of megabytes).Low-quality movies need about the same space as high-quality MP3, but a high-quality movie may require several MB per minute. Better check a sample of a movie you are interested in (or music, since music also comes in different qualities), and divide the number of megabytes by the number of minutes, to have an estimate.How many hours of what?

It depends on audio and video quality and the resilution. Most are at leas 700MB! 8MBPS connection could download this ine about 50 Minutes!
That depends a lot on what sort of data you store in those MB, for example low-quality sound, high-quality sound, low-quality video, high-quality video.
The amount of data used while listening to a 12-hour audiobook depends on the audio quality. On average, audiobooks use about 28-30 MB per hour with standard quality. So, listening to a 12-hour audiobook would use approximately 336-360 MB or 0.336-0.36 GB of data.
It depends on the quality.
That really depends on the transmission quality. A typical MP3 (stored on the computer) may have 1 MB per minute, but it may have more, or less, depending on factors that affect the quality (bitrate, sampling rate, compression). The situation is probably similar in the case of live transmission.
