Convert data storage units — bytes, KB, MB, GB, TB, PB, bits and binary units.
| Unit | Name | Value |
|---|---|---|
| 0.001 Gbit | 1 Mbit | |
| 0.01 Gbit | 10 Mbit | |
| 0.1 Gbit | 100 Mbit | |
| 1 Gbit | 1000 Mbit | |
| 5 Gbit | 5000 Mbit | |
| 10 Gbit | 10000 Mbit | |
| 50 Gbit | 50000 Mbit | |
| 100 Gbit | 100000 Mbit | |
| 1000 Gbit | 1e+06 Mbit |
Formula: Megabit = Gigabit × 1000
Multiply any gigabit value by 1000 to get megabit. One gigabit equals 1000 Mbit.
Reverse: Gigabit = Megabit × 0.001
Common gigabit values with real-world context — factor: 1 Gbit = 1000 Mbit

| 8e+05 Gbit | 8e+08 Mbit | 100 TB |
| 1e+06 Gbit | 1e+09 Mbit | 125 TB |
| 8e+06 Gbit | 8e+09 Mbit | 1 PB |
| 1e+09 Gbit | 1.000e+12 Mbit | 125 PB |
1 Gbit = 1000 Mbit. Memorize this for instant estimates.
Data storage uses both decimal (×1000) and binary (×1024) prefixes. The factor above follows the decimal (SI) standard used by storage manufacturers.
To verify: multiply your result by 0.001 to recover the original Gbit value.
Provisions broadband links rated in Mbit/s for residential and business customers.
Monitors interface utilization in Mbit/s on routers and switches.
Checks minimum bitrate requirements — Netflix 4K requires 25 Mbit/s.
Calculates bandwidth — a G.711 VoIP call uses about 0.064 Mbit/s per line.
Checks upload/download in Mbit/s to assess gaming latency and throughput.
Specs live video contribution feeds in Mbit/s for remote production.
The gigabit (Gbit) equals 1,000,000,000 bits. Gigabit internet connections (1 Gbit/s = 125 MB/s) became available to consumers in the 2010s and are now standard in fiber optic deployments.
Data center interconnects operate at 10-400 Gbit/s. Ethernet standards now reach 400 Gbit/s. A 1 Gbit/s connection can download a 1 GB file in about 8 seconds.
Interesting fact: The transatlantic cables linking Europe and North America carry over 200 Tbit/s of combined capacity — enough to download the entire Netflix library in seconds.
The megabit (Mbit) equals 1,000,000 bits and is the standard unit for broadband internet speed ratings. ISPs advertise speeds in Mbps (megabits per second), not megabytes per second.
A 100 Mbps broadband connection can theoretically download 12.5 MB per second. Standard definition video streaming requires about 3 Mbps; 4K HDR streaming needs 25 Mbps.
Interesting fact: The confusion between Mbit and MB is intentional in some marketing — a '100 Mbps' connection sounds faster than '12.5 MB/s', though they're identical.
Converting gigabit to megabit is a common task in computing, networking, and data management. Storage manufacturers, operating systems, and network equipment often express data sizes in different units — understanding the conversion is essential for comparing specifications, planning storage capacity, and interpreting network speed versus file size relationships.
As a practical reference: 5 Gbit = 5000 Mbit and 10 Gbit = 10,000 Mbit. For larger quantities, 100 Gbit = 100,000 Mbit. The reverse conversion uses the factor 0.001, so 1 Mbit = 0.001 Gbit. Note that decimal prefixes (KB=1,000, MB=1,000,000) differ from binary prefixes (KiB=1,024, MiB=1,048,576) — always check which standard your software or hardware uses.
All conversions use the internationally recognized factor of exactly 1 Gbit = 1000 Mbit, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
