Breaking a terabyte capacity down into megabytes helps when allocating space per file, per user, or per backup job.
1 TB = 1,048,576 MB using the binary standard (1 step = ×1024), or 1,000,000 MB using the decimal standard (1 step = ×1000).
To convert, multiply your TB value by the factor above. For example, 5 TB = 5,242,880 MB (binary) or 5,000,000 MB (decimal).
Operating systems and memory use the binary standard, where each unit step is 1,024. Storage manufacturers and network speeds use the decimal standard, where each step is 1,000. This converter supports both — switch modes above to match your context.
In binary (computer standard): 1 TB = 1,048,576 MB. In decimal (manufacturer standard): 1 TB = 1,000,000 MB.
Yes — TB is larger than MB. 1 TB = 1,048,576 MB (binary).
Multiply the TB value by 1,048,576 for binary, or 1,000,000 for decimal. You can also type any value into the converter above to see the result instantly.
Use binary (1024) for RAM, file sizes shown by your operating system, and programming. Use decimal (1000) for advertised drive capacities and network speeds.
