Convert Megabytes to Gigabits
Convert Megabytes (MB) to Gigabits (Gbit) instantly and accurately.
Conversion Formula
Gbit = MB × 0.008
About Megabytes
A megabyte (MB) = 1,000,000 bytes (SI). Used by all storage manufacturers and by macOS (since 10.6), iOS, and Android. Typical file sizes: JPEG photo (50 MP) = 8-20 MB; 3-min MP3 at 128 kbit/s ≈ 2.9 MB; Android productivity APK 10-150 MB; full-frame RAW photo (Sony A7R V, 61 MP) 60-120 MB. H.264/H.265 achieves 30-100× compression vs. raw video. 1 MB = 1,000,000 bytes = 1,000 KB.
About Gigabits
A gigabit (Gbit) = 10⁹ bits (SI). 1 Gbit/s Ethernet (1000BASE-T) is the enterprise baseline; 10/25/100/400 Gbit/s are data-centre standards. Bus speeds: PCIe 4.0 ×16 = 256 Gbit/s; Thunderbolt 4 = 40 Gbit/s; HDMI 2.1 = 48 Gbit/s. NVMe SSDs: PCIe 4 ≈ 57 Gbit/s; PCIe 5 > 112 Gbit/s. Submarine cables: 200 Gbit/s per wavelength × hundreds of wavelengths. 1 Gbit = 10⁹ bits = 125 MB.
