The exact value of a megabyte depends on whether it is measured in the Decimal (SI) system or the Binary system used by computers:
- In decimal system, used in storage and marketing, 1 MB = 1,0000 KB = 1,000,000 bytes.
- In binary system, used in computing and memory, 1MB = 1,024 KB = 1,048,576 bytes.
Interesting facts:
- A 3.5-inch floppy disk from the 1990s stored 1.44 MB—less than a single modern photo. Today’s USB flash drives store up to 1 TB (1,000,000 MB).
- Megabytes per second (MBps) measures file transfer speeds. But Megabits per second (Mbps) measures internet speed (8 Mbps = 1 MBps)
- A single megabyte can store a full-length novel (~400 pages) in text format
- The IBM 305 RAMAC (built in 1956) had a hard drive that stored 3.75 MB and it weighed over 1 ton
Interesting facts:
- First Consumer 1 TB Hard Drive was released in 2007 by Hitachi. Today SSDs and HDDs are available in sizes up to 100 TB
- The entire Library of Congress is estimated to be around 10 TB of text.
- A single terabyte can hold about 500 hours of HD video, roughly 200 thousands high-resolution photos or 17 thousands of MP3 music
