Why does a new 1 TB hard disk show only about 931 GB on your computer? Because storage makers count 1,000 bytes per step, while Windows and phones count 1,024. This converter works with both systems.
How to use the data storage converter
- Enter the value.
- Choose the unit to convert from and to.
- Choose the system: 1,024 for what your phone or computer shows, or 1,000 for what is printed on the box.
Units
| Unit | 1,024 system | 1,000 system |

Example
1 GB = 1,024 MB in the 1,024 system, which is 1,07,37,41,824 bytes.
A 1 TB disk (1,000,000,000,000 bytes on the box) shows as about 931 GB on a computer, and a 512 GB phone as about 477 GB.
FAQ
Is 1 GB 1,000 MB or 1,024 MB?
Both are used. Your phone and Windows use 1,024 MB. Storage makers and mobile data plans usually use 1,000 MB.
How long does a 1 GB download take on a 100 Mbps connection?
Internet speed is in megabits. 100 Mbps is 12.5 megabytes per second, so 1 GB (1,000 MB) takes about 80 seconds in ideal conditions.
What is the difference between Mb and MB?
Small b is bits and capital B is bytes. 1 byte = 8 bits, so 8 Mb = 1 MB.
