A gigabyte (GB) is 1,000 times larger than a megabyte (MB), which is 1 million bytes. A GB of data storage can store approximately 1 billion bytes. One minute of an MP3 audio file is about 1 MB, while the size of a DVD movie is roughly between 4 to 8 GB.
In 1998, the International Electrotechnical Commission (IEC) created standards for the amount of data represented by a gigabyte. The IEC requirement stipulated that a gigabyte must be equal to exactly 1,0003 bytes to differentiate it from a gibibyte, which represents 1,0243 bytes. The definition was incorporated into the International Standard of Quantities in 2009, and it is also recommended by the International System of Units (SI). However, some confusion remains because certain manufacturers measure storage capacity in gibibytes while using GB as the unit's abbreviation. In such a case, a hard drive advertised as 400 GB could be reported by an operating system as 372 GB.Learn More
Megabytes (MB) and gigabytes (MB) refer to units of measurement indicating how much data a digital storage device can hold, where one gigabyte equals 1,024 megabytes. A megabyte is approximately one million bytes, whereas a gigabyte is about one billion bytes. Megabytes and gigabytes are the most common units of measurement when specifying memory sizes in computers and other electronics.Full Answer >
A gigabyte is much larger than a megabyte. According to the National Institute of Standards and Technology, there are 1000 megabytes in a gigabyte. However, in some cases, a gigabyte is defined as 1024 megabytes.Full Answer >
There are 1,048,576 bytes in a megabyte. The prefix “mega" means one million, so approximately a million bytes are in a megabyte. Computers use a binary numeral system to measure memory size based on the power of two.Full Answer >
A megabyte is larger than a kilobyte. All digital measurements are based on bytes, and it takes more bytes to make a megabyte than a kilobyte.Full Answer >
