Mbps to MB/s

1 Mbps = 0.125 MB/s. Speeds are in bits, and 8 bits make a byte, so divide Mbps by 8 to get MB per second. Enter any amount below to convert it.

Common Mbps to MB/s conversions

Mbps	MB/s
1 Mbps	0.125
10 Mbps	1.25
100 Mbps	12.5
500 Mbps	62.5
1,000 Mbps	125
5,000 Mbps	625
10,000 Mbps	1,250
100,000 Mbps	12,500
1,000,000 Mbps	125,000

Decimal units count in thousands (1 GB = 1,000 MB). Binary units count in 1,024s (1 GiB = 1,024 MiB). Windows uses binary but labels it KB, MB and GB, which is why the same file or drive can show two different sizes.

Speeds are in bits: 8 bits make a byte, so a 100 Mbps connection moves at most 12.5 MB per second. Real downloads usually run somewhat slower than the advertised speed.
