How Many Bits in a Megabyte?
Quick Answer
There are 8,388,608 bits in a megabyte (binary).
1 MB = 1,048,576 × 8 = 8,388,608 bits
Understanding the Conversion
One megabyte (MiB) = 1,048,576 bytes × 8 bits = 8,388,608 bits. This conversion matters when comparing file sizes to connection speeds: a 10 MB file requires 83,886,080 bits to transmit. A 100 Mbps connection needs about 0.84 seconds to transfer 10 MB.
Formula
1 MB = 1,048,576 × 8 = 8,388,608 bits
Common Examples
| Description | Value |
|---|---|
| 10 MB file at 100 Mbps | ≈0.84 seconds to download |
| 1 Gbps internet speed | Downloads 125 MB per second |
| Streaming HD video (5 Mbps) | ≈37.5 MB/min |
