Convert Megabits to Bytes
Convert Megabits (Mbit) to Bytes (B) instantly and accurately.
Conversion Formula
B = Mbit × 125000
About Megabits
A megabit (Mbit) = 1,000,000 bits (SI). Everyday unit for broadband speeds: ADSL2+ up to 24 Mbit/s; VDSL2 up to 100 Mbit/s; GPON fibre 100-10,000 Mbit/s; 5G NR 100-400 Mbit/s. Streaming: Netflix 1080p = 5 Mbit/s; 4K HDR = 15-25 Mbit/s. Wi-Fi 7 = 46,120 Mbit/s theoretical. ISP 'Mbps' = megabits/s; 'MB/s' (megabytes) is 8× larger. 1 Mbit = 1,000,000 bits = 125,000 bytes.
About Bytes
The byte (B) is the fundamental addressable memory unit - 8 bits, 256 values (0-255). Standardised by the IBM System/360 (1964). UTF-8 encodes ASCII in 1 byte; Unicode in 1-4 bytes. One byte = 1 ASCII character, 1 RGB channel value, 1 PCM audio sample (8-bit). All mainstream CPU architectures (x86-64, ARM64, RISC-V) increment addresses by 1 byte. 1 byte = 8 bits = 2 nibbles.
