To convert bandwidth usage from gigabytes (GB) to megabits (Mbits), you can use the following conversion factors:

1 byte = 8 bits

1 kilobyte (KB) = 1024 bytes

1 megabyte (MB) = 1024 KB

1 gigabyte (GB) = 1024 MB

1 megabit (Mbit) = 1,000,000 bits

Here's the step-by-step conversion:

1. Start with the bandwidth usage in gigabytes (GB).
2. Convert GB to megabytes (MB) by multiplying by 1024.
3. Convert MB to megabits (Mbits) by multiplying by 8 and then by 1,000,000.

Mathematically, the conversion can be expressed as:

Bandwidth in Mbits = (Bandwidth in GB×1024×8) × 1,000,000

Let's say you have a bandwidth usage of 100 GB in a month:

Bandwidth in Mbits = (100×1024×8) × 1,000,000

Performing the calculation will give you the bandwidth usage in megabits.

Here's a table of our common bandwidths and their usage in speed equivalent. This takes into account if you are to sustain that speed over the course of the monthly billing cycle.
