What is a Data Size Converter?

A data size converter converts digital storage, memory, and bandwidth units across SI decimal ($10^3$) and IEC binary ($2^{10}$) computing standards.

Frequently Asked Questions

In standard decimal (SI): 1 GB = 1,000 MB. In binary (IEC / Windows): 1 GiB = 1,024 MiB.

1 Byte (B) = 8 Bits (b). Network speeds are usually measured in bits per second (Mbps), while file sizes are measured in bytes (MB).

Hard drive manufacturers use decimal gigabytes (1,000,000,000,000 bytes), whereas Windows operating systems measure in binary GiB (divided by 1024^3 = 931.32 GiB).

1 KB = 1,000 bytes (SI base 10); 1 KiB = 1,024 bytes (IEC binary base 2).

Divide by 8: 100 Mbps ÷ 8 = 12.5 Megabytes per second (MB/s) maximum theoretical download speed.

1 TB = 1,000 GB (or 1,024 GiB).

Petabyte (PB = 1,000 TB), Exabyte (EB = 1,000 PB), Zettabyte (ZB = 1,000 EB), Yottabyte (YB = 1,000 ZB).

4K video at 60fps typically uses 300 to 400 MB per minute of footage (~20–25 GB per hour) depending on bitrate.
