Megabit to Gigabit Converter
Digital storage · unit-converter
Convert Megabit to Gigabit 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.

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 Gigabit
Gigabits uses the same byte-based factors as the main Digital Storage Converter.
How to convert megabits to gigabits
1 megabit is equal to 0.001 gigabit in this tool (values are compared in byte-equivalents):
1 mbit = (125,000 B ÷ 125,000,000 B) gbit = 0.001 gbit
Each megabit counts as 125,000 bytes and each gigabit as 125,000,000 bytes, so one mbit equals 125,000 ÷ 125,000,000 gbit = 0.001 gbit.
Let d(mbit) be the numeric amount in Megabit (mbit), and d(gbit) the amount in Gigabit (gbit). Then:
d(gbit) = d(mbit) × (125,000 / 125,000,000)
Equivalently, divide by how many mbit fit into one gbit (bytes per gbit divided by bytes per mbit):
d(gbit) = d(mbit) ÷ 1000
Or: gigabit = megabit ÷ 1000
Examples
Example #1: Convert 1 mbit to gigabit
1 mbit = 1 mbit × (125,000/125,000,000) gbit = 0.001 gbit
1 mbit = 1 mbit ÷ 1000 = 0.001 gbit
Example #2: Convert 10 mbit to gigabit
10 mbit = 10 mbit × (125,000/125,000,000) gbit = 0.01 gbit
10 mbit = 10 mbit ÷ 1000 = 0.01 gbit
Summary
To convert Megabit to Gigabit, multiply the value in mbit by the ratio of bytes per mbit divided by bytes per gbit. Equivalently: value_gbit = value_mbit × (125000 / 125000000). Numerically, 1 mbit equals 0.001 gbit.
Relationship context
Both units are bit-based units (converted via 8 bits per byte). Factors are fixed relative to one byte, so conversions are exact in floating-point arithmetic for this tool. The factor from Megabit to Gigabit is 1.000000e-3 (1 mbit = 0.001 gbit).
