Megabyte to Gigabyte Converter
Digital storage · unit-converter
Convert Megabyte to Gigabyte with fixed input and output units, a step-by-step formula line, and reference tables. This hub uses decimal byte units (kB, MB, GB, …) and decimal megabits; the main converter also includes binary (KiB, MiB, …) units.

From: Megabyte (mb)
To: Gigabyte (gb)
About Megabyte
The megabyte (MB) is 10⁶ bytes (decimal). File sizes and download speeds are often discussed in MB alongside megabits per second (Mb/s) for networks.
About Gigabyte
The gigabyte (GB) here is a decimal unit: 1 GB = 10⁹ bytes. Storage marketing and many OS dialogs use decimal GB; some systems still show binary (GiB) labels—check context when comparing numbers.
How to convert megabytes to gigabytes
1 megabyte is equal to 0.001 gigabyte in this tool (values are compared in byte-equivalents):
1 mb = (1,000,000 B ÷ 1,000,000,000 B) gb = 0.001 gb
Each megabyte counts as 1,000,000 bytes and each gigabyte as 1,000,000,000 bytes, so one mb equals 1,000,000 ÷ 1,000,000,000 gb = 0.001 gb.
Let d(mb) be the numeric amount in Megabyte (mb), and d(gb) the amount in Gigabyte (gb). Then:
d(gb) = d(mb) × (1,000,000 / 1,000,000,000)
Equivalently, divide by how many mb fit into one gb (bytes per gb divided by bytes per mb):
d(gb) = d(mb) ÷ 1000
Or: gigabyte = megabyte ÷ 1000
Examples
Example #1: Convert 1 mb to gigabyte
1 mb = 1 mb × (1,000,000/1,000,000,000) gb = 0.001 gb
1 mb = 1 mb ÷ 1000 = 0.001 gb
Example #2: Convert 10 mb to gigabyte
10 mb = 10 mb × (1,000,000/1,000,000,000) gb = 0.01 gb
10 mb = 10 mb ÷ 1000 = 0.01 gb
Summary
To convert Megabyte to Gigabyte, multiply the value in mb by the ratio of bytes per mb divided by bytes per gb. Equivalently: value_gb = value_mb × (1000000 / 1000000000). Numerically, 1 mb equals 0.001 gb.
Relationship context
Both units are byte-based units (decimal SI: kB, MB, GB, …). Factors are fixed relative to one byte, so conversions are exact in floating-point arithmetic for this tool. The factor from Megabyte to Gigabyte is 1.000000e-3 (1 mb = 0.001 gb).
