💾 Data Size Converter

About this Data Size Converter

This data converter uses the binary counting that computers themselves use: 1 KB = 1,024 bytes, 1 MB = 1,024 KB, and so on. It includes bits as well, because internet speeds are sold in bits per second while files are measured in bytes — an 8-to-1 difference that explains many slow-looking downloads.

How to use it

1. Enter the data size.
2. Pick the unit it is in and the unit you want.
3. Click Convert — the table shows bits through terabytes together.

Example

1 GB is 1,024 MB, and a 100 Mbps internet line can download at most 12.5 MB per second because 100 ÷ 8 = 12.5.

Frequently asked questions

Why 1024 and not 1000?

Computers count in powers of two, and 2¹⁰ = 1,024 is the nearest power to a thousand. Hard-drive makers sometimes use 1,000 instead, which is why a '500 GB' drive shows about 465 GB in your computer.

How many bits are in a byte?

Exactly 8 bits make 1 byte — remember to divide internet speeds (bits) by 8 to compare them with file sizes (bytes).
