Convert Megabits to Kilobits (Mbit to kbit)
1 megabit (Mbit) = 1000 kilobits (kbit). 1 kbit = 0.001 Mbit. Example: 15 Mbit = 15 × 1000 = 15000 kbit.

How to Convert Megabit to Kilobit
- 1 Mbit = 1000 kbit
- 1 kbit = 0.001 Mbit
- Example: convert 15 Mbit to kbit: 15 Mbit = 15 × 1000 kbit = 15000 kbit
Formula
kbit = Mbit × 1000
Derivation from SI units:
- 1 Mbit = 10⁶ bits.
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 Mbit = 1000000 bit ÷ 1000 bit per kbit = 1000 kbit
Both units are defined exactly, so the factor is exact. Megabit definition: megabit; Kilobit definition: kilobit.
Worked examples
- A reading of 16 Mbit converts to 16000 kbit.
16 Mbit × 1000 = 16000 kbit - A value of 128 Mbit is 128000 kbit.
128 Mbit × 1000 = 128000 kbit
