What is MB and GB?
A megabyte is a unit of digital information consisting of 1,000,000 bytes, or 1,048,576 bytes. A gigabyte is a unit of computer information which is equivalent to 1,000,000,000 bytes, or 1,073,741,824 bytes. So, a gigabyte (GB) is one thousand times bigger than a megabyte (MB).
What does KB and GB mean?
A kilobyte (KB) is 1,000 bytes, and one megabyte (MB) is 1,000 kilobytes. One gigabyte (GB) is equal to 1,000 megabytes, while a terabyte (TB) is 1,000 gigabytes.
How big is a MB of data?
A megabyte is 106 or 1, 000, 000 bytes and is abbreviated as “MB”. 1 MB is technically 1, 000, 000 bytes, therefore, megabytes are often used synonymously with mebibytes, which contain exactly 1, 048, 576 bytes (220). Megabytes are mostly used to measure the size of large files.
Is 1 MB a lot of data?
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.
How many width and height is 1 MB?

What is a normal image size?
4 x 6 or 5 x 7 in. These sizes are standard and popular photo sizes, typically for displaying photography or smaller artwork.
What image size should I use?
It’s best to look at the pixel dimension of your images as you’re making them. As long as they’re at least about 1024 pixels wide (for a horizontal image) they should be fine for teaching. The standard resolution for web images is 72 PPI (often called “screen resolution”).
How many MB is a high resolution photo?
Typically images will be supplied as JPEGs, and an A4 (210mm x 297mm or 8¼” x 11¾”) image at 72 ppi will create a JPEG of approximately 500kb or half a megabyte. Remember though – to use that image in print we need the image to be 300 ppi, and at that resolution the JPEG will be around 3.5 Megabytes.
How do you reduce the MB size of a photo?
The Photo Compress app available at Google Play does the same thing for Android users. Download the app and launch it. Select the photos to compress and adjust the size by choosing Resize Image. Be sure to keep the aspect ratio on so the resizing doesn’t distort the height or width of the photo.
