Use the Mbps input for now. Future updates may add Gbps/Tbps.

Why is MB/s smaller than Mbps?

Because bytes have 8 bits. Divide Mbps by 8 to get MB/s (using decimal units).

Does this include overhead?

No. It’s a pure unit conversion. Real throughput can be lower due to protocol overhead.

Are these decimal or binary units?

Decimal (1 MB = 1,000,000 bytes). Binary (MiB/s) values will be slightly lower.

Divide Mbps by 1000 for Gbps, or multiply by 1000 to go from Gbps to Mbps.

Data Transfer Rate Converter

Convert Mbps, MB/s, and KB/s values to compare network and storage speeds.

Results

Mbps: 150.00
MB/s: 18.75
KB/s: 18750.00

How to use this calculator

Enter a value and choose its unit (Mbps, MB/s, or KB/s).
We normalize to bits per second and convert to all other units.
Use the outputs to compare specs across devices and services.

Inputs explained

Value: Throughput number you have from a spec sheet or speed test.
Unit: Unit that value is expressed in (Mbps, MB/s, or KB/s).

How it works

We normalize your input to bits per second and then convert back to Mbps, MB/s, and KB/s.

Formula

bps = value × conversion factor (depending on unit)

When to use it

Comparing ISP speeds (Mbps) with camera or SSD specs (MB/s).
Checking if network links can sustain backup or streaming bitrates.
Sanity-checking speed tests vs. vendor claims.

Tips & cautions

Remember 1 byte = 8 bits. Mbps numbers are eight times MB/s for the same throughput.
Storage vendors sometimes use binary units (MiB/s); this tool uses decimal for quick estimates.
Round to one or two decimals for easier communication with non-technical stakeholders.
Decimal units only; binary (MiB/s) will differ slightly.
Does not account for protocol overhead or duplex differences.
No Gbps/Tbps outputs—convert manually by dividing or multiplying by 1000.

Worked examples

100 Mbps to MB/s

100 Mbps ≈ 12.5 MB/s

50 MB/s to Mbps

50 MB/s ≈ 400 Mbps

Deep dive

This data transfer rate converter flips between Mbps, MB/s, and KB/s. Enter any rate and unit to see the equivalents so you can compare network, storage, and camera specs.

Use it to align ISP plans with hardware throughput or to sanity-check speed tests. It uses decimal units (1 MB = 1,000,000 bytes); binary units will be slightly different.

FAQs

What about gigabit?: Use the Mbps input for now. Future updates may add Gbps/Tbps.
Why is MB/s smaller than Mbps?: Because bytes have 8 bits. Divide Mbps by 8 to get MB/s (using decimal units).
Does this include overhead?: No. It’s a pure unit conversion. Real throughput can be lower due to protocol overhead.
Are these decimal or binary units?: Decimal (1 MB = 1,000,000 bytes). Binary (MiB/s) values will be slightly lower.
Can I get Gbps?: Divide Mbps by 1000 for Gbps, or multiply by 1000 to go from Gbps to Mbps.
