How many MB are in a GB?

In decimal notation there are exactly 1000 MB in 1 GB, because each step is a multiple of 1000. In binary notation there are 1024 MiB in 1 GiB. The tool lets you switch between both answers, since the correct one depends on the context.

What is the difference between GB and GiB?

A gigabyte (GB) is 1,000,000,000 bytes, while a gibibyte (GiB) is 1,073,741,824 bytes. The 73.7 million byte difference comes from using powers of 1000 versus powers of 1024, and it explains why a 1 TB drive appears as about 931 GiB.

How many bits are in a byte?

There are 8 bits in 1 byte. This is why a 100 Mbps internet connection moves about 12.5 MB of data per second at full speed.

Why does my 1 TB drive only show 931 GB?

The drive holds 1,000,000,000,000 bytes, which the manufacturer correctly labels as 1 TB using decimal prefixes. Your operating system counts in 1024-based units, so it reports roughly 931 GiB. Both numbers describe the same physical capacity.

Can I convert bits to bytes with this tool?

Yes. Both bits and bytes are available in the unit lists, with 1 byte equal to 8 bits. This is useful when comparing storage capacities with data rates.

Is my data sent to a server?

No. All calculations happen in your browser with JavaScript. Nothing you enter is uploaded, stored or logged.

Which unit should I use for a cloud storage plan?

Check how the provider labels its quotas. Most plans and drive manufacturers use decimal GB, while operating systems and many Linux tools report binary GiB. Match your context and convert between them when comparing.

A petabyte (PB) is 1,000,000,000,000,000 bytes in decimal, or 1,048,576 gigabytes. It is roughly the scale of large data centers and film archives, and this tool converts it to every smaller unit.

How do I convert TB to GB?

In decimal mode, multiply the terabyte value by 1000, because 1 TB equals 1,000 GB. In binary mode, multiply by 1024 because 1 TiB equals 1024 GiB. Enter the value and pick the units to let the tool apply the right factor automatically.

Why do file sizes never look like the drive label?

Drives are labelled in decimal units (1,000-based) while file systems count in binary units (1,024-based). The same 500 GB drive therefore reports about 465 GiB, and file sizes follow that binary arithmetic.
