MB to TB Converter
Convert megabytes to terabytes — one million megabytes make a terabyte. Results update as you type; exact factors shown.
One megabyte (10⁶) is 0 terabyte (10¹²) — see the exact factor, not a rounded rule of thumb.
How the mb to tb converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about data conversion
How many MB in a TB?
1,000,000 on the decimal definition.
What is 500,000 MB in TB?
0.5 TB.
Is a terabyte 1,024 GB?
Not on the decimal definition, where it is 1,000 GB. The 1,024 figure is the tebibyte, TiB.
How much is a terabyte in practice?
Roughly 250,000 photos from a modern phone, or around 40 hours of 4K video.
Why do backups need more space than the data?
Versioning and metadata. Plan for well over the raw figure if you keep history.
