Data converters

14 converters. Bits, bytes, megabytes, gigabytes and more, decimal and binary, each with the formula and the math worked out with your numbers.

File sizes

Megabytes to gigabytes MB → GB 500 MB = 0.5 GB Gigabytes to megabytes GB → MB 1.5 GB = 1,500 MB Gigabytes to terabytes GB → TB 500 GB = 0.5 TB Terabytes to gigabytes TB → GB 2 TB = 2,000 GB Kilobytes to megabytes kB → MB 2,500 kB = 2.5 MB Megabytes to kilobytes MB → kB 2 MB = 2,000 kB

Binary units

Gigabytes to gibibytes GB → GiB 500 GB = 465.66 GiB Gibibytes to gigabytes GiB → GB 16 GiB = 17.18 GB Terabytes to tebibytes TB → TiB 2 TB = 1.82 TiB Mebibytes to megabytes MiB → MB 100 MiB = 104.86 MB

Bits & bytes

Megabits to megabytes Mb → MB 100 Mb = 12.5 MB Megabytes to megabits MB → Mb 50 MB = 400 Mb Bytes to bits B → bit 1,024 B = 8,192 bits Bits to bytes bit → B 64 bits = 8 B

Data units at a glance

Unit	Symbol	In bytes	Defined as
Bit	bit	0.125	1/8 B
Megabit	Mb	125,000	1,000,000 bit
Byte	B	1	8 bit
Kilobyte	kB	1,000	1,000 B
Megabyte	MB	1,000,000	1,000 kB
Gigabyte	GB	1,000,000,000	1,000 MB
Terabyte	TB	1,000,000,000,000	1,000 GB
Kibibyte	KiB	1,024	1,024 B
Mebibyte	MiB	1,048,576	1,024 KiB
Gibibyte	GiB	1,073,741,824	1,024 MiB
Tebibyte	TiB	1,099,511,627,776	1,024 GiB

Storage makers count in thousands (1 GB = 1,000 MB), while many computers count in 1,024s and call the result “GB” too. The binary units (KiB, MiB, GiB, TiB) make that difference explicit.
