How many Kbps are in one Mbps?
A megabit per second equals 1,000 kilobits per second. Network and media speeds follow the decimal SI system, where mega stands for a million and kilo for a thousand, so each Mbps is simply a thousand Kbps.
Kbps = Mbps × 1,000To go back, divide by 1,000.
Because the factor is a clean power of ten, the conversion only shifts the decimal point three places to the right. No rounding is involved unless your input has more than a few decimals.
Difference between Mbps and Kbps
Both measure bits per second, so they describe the same quantity at different sizes. Mbps is the scale for modern broadband and video; Kbps is the finer scale used for audio bitrates, voice calls and the low-bandwidth links of earlier decades. Converting to Kbps is handy when a service quotes a requirement in kilobits, such as a voice codec, while your plan is given in megabits.
Be careful with capital letters. A lowercase b stands for bit, and an uppercase B for byte, so Kbps and KBps are not interchangeable: the second is eight times larger.
How to convert Mbps to Kbps
- Take the speed in megabits per second.
- Multiply it by 1,000, which moves the decimal point three places to the right.
- Read the answer in kilobits per second.
The converter prints up to four decimal places and no thousands separators, so 1.5 Mbps appears as 1500 Kbps.
Example: sizing a voice and video setup
Suppose a video-conferencing app asks for 1.2 Mbps per participant and a voice-only app for 0.064 Mbps. In kilobits those are 1.2 × 1,000 = 1,200 Kbps and 0.064 × 1,000 = 64 Kbps. With a 4.5 Mbps (4,500 Kbps) connection you could host three video participants (3,600 Kbps) and still have 900 Kbps spare for fourteen voice-only ones (896 Kbps).

Common mistakes
- Multiplying by 1,024. That belongs to binary storage prefixes, not to data rates. The factor here is 1,000.
- Swapping the direction. Kbps numbers are always bigger than the Mbps number they come from. If your result is smaller, you divided instead of multiplying.
- Mixing in bytes. If a requirement is in KB/s or MB/s, convert to bits first by multiplying by eight, then use the factor of 1,000.
The reverse conversion is the Kbps to Mbps converter. For turning a speed into a transfer time, use the download time calculator.
Frequently asked questions
How many Kbps are in 1 Mbps?
1,000. Multiply a value in Mbps by 1,000 to get Kbps.
How many Kbps is 0.5 Mbps?
0.5 × 1,000 = 500 Kbps.
Does Mbps to Kbps use 1,024?
No. Data rates use decimal SI prefixes, so the factor is exactly 1,000.
Is Kbps the same as KB/s?
No. Kbps counts kilobits per second and KB/s counts kilobytes per second. A kilobyte holds eight kilobits, so KB/s figures are one eighth as large.
