Decimal vs. binary — why 1 GB isn't always 1 GB

This page uses the decimal (SI) convention: 1 KB = 1000 bytes, 1 MB = 1000 KB, 1 GB = 1000 MB, and 1 TB = 1000 GB. That is how hard-drive and SSD makers, Google, and macOS state capacity. Windows and RAM, by contrast, use the binary (IEC) convention, where 1 KiB = 1024 bytes and 1 GiB = 1024 MiB. The gap grows with size: 1 GiB = 1.073741824 GB, which is why a 1 TB drive (1000 GB) shows as about 931 GiB in Windows. No storage is missing — these are simply two different measuring systems.

Frequently asked questions

How many KB are in 1 bytes?

1 bytes equals 0.001 KB.

How many KB are in 2 bytes?

2 bytes equal 0.002 KB.

How do I convert bytes to KB?

Divide the amount in bytes by 1000 to get KB.

Is 1 GB equal to 1000 MB or 1024 MB?

On this page we use the decimal (SI) convention: 1 GB = 1000 MB, 1 MB = 1000 KB, and so on. That is what storage manufacturers, Google, and macOS use. The binary (IEC) convention (1 GiB = 1024 MiB), used by Windows and RAM, gives different numbers: 1 GiB = 1.073741824 GB.

Why does my computer show less space?

Hard-drive and SSD makers state capacity in decimal units (1 TB = 1000 GB = 1,000,000,000,000 bytes). Windows, however, counts in binary and reports the same capacity as GiB (dividing by 1024 instead of 1000). So a 1 TB drive shows as about 931 GiB in Windows — no space is missing, it is just a different unit (1 GiB = 1.073741824 GB). macOS has shown decimal GB since OS X 10.6.

What are these data-storage units used for?

Bytes and bits are the smallest units — 1 byte = 8 bits; bits per second measure bandwidth. Kilobytes (KB) and megabytes (MB) describe documents, photos, and songs; gigabytes (GB) and terabytes (TB) describe hard drives, SSDs, and data plans. All values here are decimal (SI).
