Real-world reference
A consumer NAS typically holds 4–32 TB across multiple drives. 1 TB of cloud storage is the standard 'pro' tier on most consumer plans. In megabytes, that gives you: 1 TB = 1000000 MB, 10 TB = 10000000 MB, 100 TB = 100000000 MB.
Frequently asked questions
- How many megabytes are in 1 terabyte?
- 1 terabyte equals 1000000 megabytes.

About the terabyte and the megabyte
The megabyte
The megabyte (MB) equals 1,000,000 bytes (decimal) or 1,048,576 bytes (binary, formally 'mebibyte' MiB — a roughly 5% difference). Used for music files, photographs, and most everyday document sizes.
