Convert Megabits to Bytes (Mbit to B)
1 megabit (Mbit) = 125000 bytes (B). 1 B = 0.000008 Mbit. Example: 15 Mbit = 15 × 125000 = 1875000 B.

How to Convert Megabit to Byte
- 1 Mbit = 125000 B
- 1 B = 0.000008 Mbit
- Example: convert 15 Mbit to B: 15 Mbit = 15 × 125000 B = 1875000 B
Formula
B = Mbit × 125000
Derivation from SI units:
- 1 Mbit = 10⁶ bits.
- 1 byte = 8 bits (an octet).
- 1 Mbit = 1000000 bit ÷ 8 bit per B = 125000 B
Both units are defined exactly, so the factor is exact. Megabit definition: megabit; Byte definition: byte.
Worked examples
- A reading of 16 Mbit converts to 2000000 B.
16 Mbit × 125000 = 2000000 B - A value of 128 Mbit is 16000000 B.
128 Mbit × 125000 = 16000000 B
