Megabit to Gigabyte Converter
Digital storage · unit-converter
Convert Megabit 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: Megabit (mbit)
To: Gigabyte (gb)
About Megabit
The megabit (Mb) is 10⁶ bits. Dividing by 8 gives byte-equivalents for data size; ISP speeds (Mbps) refer to megabits per second, not megabytes.
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 megabits to gigabytes
1 megabit is equal to 0.000125 gigabyte in this tool (values are compared in byte-equivalents):
1 mbit = (125,000 B ÷ 1,000,000,000 B) gb = 0.000125 gb
Each megabit counts as 125,000 bytes and each gigabyte as 1,000,000,000 bytes, so one mbit equals 125,000 ÷ 1,000,000,000 gb = 0.000125 gb.
Let d(mbit) be the numeric amount in Megabit (mbit), and d(gb) the amount in Gigabyte (gb). Then:
d(gb) = d(mbit) × (125,000 / 1,000,000,000)
Equivalently, divide by how many mbit fit into one gb (bytes per gb divided by bytes per mbit):
d(gb) = d(mbit) ÷ 8000
Or: gigabyte = megabit ÷ 8000
Examples
Example #1: Convert 1 mbit to gigabyte
1 mbit = 1 mbit × (125,000/1,000,000,000) gb = 0.000125 gb
1 mbit = 1 mbit ÷ 8000 = 0.000125 gb
Example #2: Convert 10 mbit to gigabyte
10 mbit = 10 mbit × (125,000/1,000,000,000) gb = 0.00125 gb
10 mbit = 10 mbit ÷ 8000 = 0.00125 gb
Summary
To convert Megabit to Gigabyte, multiply the value in mbit by the ratio of bytes per mbit divided by bytes per gb. Equivalently: value_gb = value_mbit × (125000 / 1000000000). Numerically, 1 mbit equals 0.000125 gb.
Relationship context
You are converting between bit-based units (converted via 8 bits per byte) (Megabits) and byte-based units (decimal SI: kB, MB, GB, …) (Gigabytes). Bit units are mapped through 8 bits per byte, then scaled with the same decimal prefixes as byte units. The numeric factor is 1.250000e-4.
