The calculation, without hidden assumptions
Network plans are usually advertised in bits per second while browsers, download tools and storage devices often report bytes per second. The lowercase b versus uppercase B changes the result by a factor of eight, and decimal prefixes such as MB are not the same as binary MiB. MAXScanner keeps those distinctions visible, supports decimal and binary rate families side-by-side, and adds practical GB/hour and TB/day throughput equivalents without pretending a link rate is the same as real application throughput.
How to use this calculator
Enter the advertised or measured data rate and choose the exact bit/byte and decimal/binary unit.
Choose the target unit—for example Mbps to MB/s—and compare the full equivalents before assuming an Internet-plan figure should match a download-manager number.
Use GB/hour or TB/day as ideal transfer-volume context, then move to Data Transfer Time when you know a real file size and want an elapsed-time estimate.
Where people use it
- •Internet plan Mbps to download MB/s checks
- •Storage and network throughput comparisons
- •Backup/window capacity planning
- •Separating SI decimal rates from IEC binary rates
Example: 100 Mbps to MB/s
One byte is eight bits, so 100 megabits per second divided by eight equals 12.5 megabytes per second in decimal units. At that ideal constant rate, about 45 GB transfers in one hour.
What the result does not assume
- •A rated link speed is not guaranteed application throughput. Protocol overhead, congestion, Wi-Fi conditions, storage performance and server limits can reduce observed transfer rate.
- •Decimal MB/s and binary MiB/s are different units. MAXScanner keeps SI k/M/G/T prefixes separate from IEC Ki/Mi/Gi prefixes.
Frequently asked questions
How many MB/s is 100 Mbps?+
Exactly 12.5 MB/s in decimal units before any real-world overhead.
Why is Mbps different from MB/s?+
Mbps uses megabits per second while MB/s uses megabytes per second. Eight bits make one byte.
Is MB/s the same as MiB/s?+
No. MB/s uses decimal powers of 1,000, while MiB/s uses binary powers of 1,024.
Can I use this to estimate download time?+
Use the converted rate here, then use the Data Transfer Time Calculator with the actual file size for a direct elapsed-time estimate.
