Bytes to Mbps

Real‑time, accurate Bytes to Mbps Converter. Choose Decimal (SI) or Binary (IEC) for KB/MB scaling.

Decimals

KB/MB scaling follows the selected standard (SI or IEC).

Mbps (10⁶ b/s)

Mbps uses decimal bits by convention: 1 Mbps = 1,000,000 bits/s.

Useful notes & tips

  • SI vs IEC: Choose SI for KB=1000 B, MB=1,000,000 B; choose IEC for KiB=1024 B, MiB=1,048,576 B.
  • Why Mbps? ISPs advertise speeds in Mbps (decimal) — converting helps estimate download time from app speeds shown in MB/s.
  • Download time rough rule: time (s) ≈ size (MB) × 8 ÷ speed (Mbps).

How the Bytes to Mbps conversion works

Bits vs Bytes: 1 Byte = 8 bits. Internet speeds like Mbps are measured in bits per second (decimal), while file sizes and app speeds often use Bytes per second with either decimal (SI) or binary (IEC) prefixes.

Formula (SI)

Mbps = (B/s × 8) ÷ 1,000,000

MB/s = (B/s) ÷ 1,000,000

Formula (IEC)

MiB/s = (B/s) ÷ 1,048,576

Mbps output still uses decimal bits by convention.

Example

1 Mbps = 1,000,000 b/s = 125,000 B/s. In binary, 125,000 B/s ≈ 122.07 KiB/s.

Table uses SI for KB/MB and IEC for KiB/MiB; Mbps is decimal (1,000,000 b/s).

Frequently Asked Questions

How do I convert Bytes per second (B/s) to Megabits per second (Mbps)?
Use Mbps = (B/s × 8) ÷ 1,000,000 (SI). If you prefer binary, use Mibps = (B/s × 8) ÷ 1,048,576.
What’s the difference between MB/s and Mbps?
MB/s is megabytes per second; Mbps is megabits per second. 1 byte = 8 bits, so MB/s × 8 = Mbps (SI).
Do you support SI vs IEC (binary) units?
Yes. SI uses powers of 10 (k=1,000, M=1,000,000) while IEC uses powers of 2 (Ki=1,024, Mi=1,048,576). The converter lets you choose.
Is 1 MB/s equal to 8 Mbps?
Yes, using SI definitions. Example: 12.5 MB/s ≈ 100 Mbps.
How do I convert MB/s to Mbps quickly?
Multiply by 8. Example: 20 MB/s × 8 = 160 Mbps.
How many bits are in a byte?
Exactly 8 bits per byte.
Why is my ISP speed in Mbps but my download app shows MB/s?
ISPs advertise in Mbps (bits). Many apps show MB/s (bytes). Divide the Mbps value by 8 to estimate MB/s (SI).
