How Many Megabytes in a Gigabyte

A gigabyte is how much information is stored in data files that could fit on a laptop’s hard drive--a gigabyte is equivalent to 1,000 megabytes.


Many of these estimates come directly from an about.com article on mobile data with data compiled from various carrier estimates of the average smartphone data usage of specific smartphone activities. We also used numerous other sources to update those numbers where necessary. These figures are based on using mobile data on your smartphone and don’t take tethering into account. Mobile versions of websites are designed to be less data heavy than their non-mobile counterparts.

Pop quiz…how many MB in a GB again? Well done, Pointdexter: the answer to “how many megabytes in a gig” is roughly 1000 MB. That amount is what we refer to as the “large bucket,” which, for anyone with regular access to Wi-Fi, means worrying a lot less about mobile data. If there’s more than one light mobile data user on an account, shareable data (such as what’s available on our Flex plan) can help you save even more. (Source: ting.com)


One kilobyte (KB) is a collection of about 1000 bytes. A page of ordinary Roman alphabetic text takes about 2 kilobytes to store (about one byte per letter). A typical short email would also take up just 1 or 2 kilobytes. Text is one of the most naturally compact types of data at about one byte required to store each letter. In non-roman alphabets, such as Mandarin, the storage takes up 2 or 4 bytes per "letter" which is still pretty compact compared to audio and images. (Source: web.stanford.edu)

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. Audio and image and video data typically stored in "compressed" form, MP3 being an example. We'll talk about how compression works later. A data CD disk stores about 700 MB. The audio on a CD is not compressed, which is why it takes so much more space than the MP3. The series of bits are represented as spiral path of tiny pits in the silver material in the disk. Imagine that each pit is interpreted as a 0, and the lack of a pit is a 1 as the spiral sequence is read. Fun fact: the whole spiral on a CD is over 5km long. (Source: web.stanford.edu)
