Convert data storage units — bytes, KB, MB, GB, TB, PB, bits and binary units.
| Unit | Name | Value |
|---|---|---|
| 0.001 GB | 8 Mbit | |
| 0.01 GB | 80 Mbit | |
| 0.1 GB | 800 Mbit | |
| 1 GB | 8000 Mbit | |
| 5 GB | 40000 Mbit | |
| 10 GB | 80000 Mbit | |
| 50 GB | 400000 Mbit | |
| 100 GB | 800000 Mbit | |
| 1000 GB | 8e+06 Mbit |
Formula: Megabit = Gigabyte × 8000
Multiply any gigabyte value by 8000 to get megabit. One gigabyte equals 8000 Mbit.
Reverse: Gigabyte = Megabit × 0.000125
Common gigabyte values with real-world context — factor: 1 GB = 8000 Mbit

1 GB = 8000 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 0.000125 to recover the original GB value.
Specifies app download sizes, database backup sizes, and API payload limits in GB.
Compares phone, tablet, and laptop storage in GB when purchasing devices.
Provisions storage buckets, database sizes, and VM disk images in GB.
Estimates project sizes — 1 minute of 4K RAW video uses about 6 GB.
Monitors disk usage, quota limits, and backup sizes across GB-scale storage.
Handles dataset sizes in GB for training, validation, and test splits.
The gigabyte (GB) equals 1,000,000,000 bytes (decimal) or 1,073,741,824 bytes (binary). The distinction matters: Windows historically reported drive sizes in binary gigabytes, while drive manufacturers used decimal — causing the perennial 'missing space' confusion.
Gigabytes define modern consumer storage: smartphone apps, photos, and videos. A typical smartphone photo is 3-5 MB, so 1 GB holds roughly 200-300 photos. A 4K movie takes 60-100 GB.
Interesting fact: The first 1 GB hard drive (IBM 3380, 1980) weighed 250 kg and cost $40,000. Today, a 1 GB microSD card costs about $0.10.
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 gigabyte 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 GB = 40,000 Mbit and 10 GB = 80,000 Mbit. For larger quantities, 100 GB = 800,000 Mbit. The reverse conversion uses the factor 0.000125, so 1 Mbit = 0.000125 GB. 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 GB = 8000 Mbit, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
