QuackyardData Size Converter
Convert bits, bytes, kB and MB against KiB, MiB and GiB exactly, and time a download.
A number with a unit: 1.5 GB, 700 MiB, 8 Gb. Typed all lowercase, mb or kib reads as bytes; mixed, as in Mb, it reads as bits.
1.5 GB is 1,500,000,000 bytes
| Unit | Value | In words |
|---|---|---|
| Bytes, decimal (SI) — each step ×1,000 | ||
| B | 1,500,000,000 | bytes |
| kB | 1,500,000 | kilobytes |
| MB | 1,500 | megabytes |
| GB | 1.5 | gigabytes |
| TB | 0.0015 | terabytes |
| PB | 0.0000015 | petabytes |

SI units count by thousands and IEC units by 1,024s: 1 GB is 1,000,000,000 bytes, while 1 GiB is 1,073,741,824 — 7.37% more. Drive makers count in SI units and operating systems report IEC ones, so a drive sold as 1 TB shows up as about 931.32 GiB. This page reads KB as 1,000 bytes; some systems mean 1,024.
