View table →Frequently Asked Questions
How many MB are in 1 GB?
One gigabyte equals 1000 megabytes (decimal/SI). Going the other way, 1 MB equals 0.001 GB.
How many GB are in 1 TB?
One terabyte equals 1000 gigabytes (decimal/SI), or 1,000,000 MB. Going the other way, 1 GB equals 0.001 TB.
Is 1 GB equal to 1000 MB or 1024 MB?
On this site we use the decimal (SI) convention: 1 GB = 1000 MB. Drive makers, Google, and macOS count this way. Windows and RAM use the binary (IEC) convention (1 GiB = 1024 MiB), where 1 GiB = 1.073741824 GB.
How many bits are in 1 byte?
One byte is made of 8 bits. Data rates are often quoted in bits per second, whereas file sizes are quoted in bytes.
Why does my computer show less space?
A 1 TB drive (1000 GB, decimal) shows as about 931 GiB in Windows because Windows divides by 1024 in binary. No space is missing — it is just a different unit (1 GiB = 1.073741824 GB).
