Mbps to GB per Hour Data Calculator
Enter a network rate in Mbps to see its ideal hourly and daily data volume. Use the result for transfers and capacity planning, not as a prediction that every connection will stay saturated.
The decimal-unit shortcut is Mbps × 0.45. This assumes the full rate carries data continuously for 3,600 seconds with no idle time or protocol overhead.

How it works
Transparent math, not a mystery result.
NetCalcKit uses standard decimal network units unless the page explicitly says otherwise. The calculator updates in your browser and labels ideal estimates separately from real-world conditions.
Quick reference
Mbps to GB per hour and per day table
The table assumes each rate stays fully occupied. It uses decimal units, so 1 GB equals 1,000 MB. Actual usage is lower whenever the connection is idle or cannot sustain the listed payload rate.
| Rate | Per minute | Per hour | Per 24 hours |
|---|---|---|---|
| 1 Mbps | 7.5 MB | 0.45 GB | 10.8 GB |
| 5 Mbps | 37.5 MB | 2.25 GB | 54 GB |
| 10 Mbps | 75 MB | 4.5 GB | 108 GB |
| 25 Mbps | 187.5 MB | 11.25 GB | 270 GB |
| 50 Mbps | 375 MB | 22.5 GB | 540 GB |
| 100 Mbps | 750 MB | 45 GB | 1,080 GB |
| 500 Mbps | 3.75 GB | 225 GB | 5,400 GB |
| 1,000 Mbps | 7.5 GB | 450 GB | 10,800 GB |
Why × 0.45 works
From megabits each second to gigabytes each hour
Divide Mbps by eight to get megabytes per second, multiply by 3,600 seconds, then divide by 1,000 megabytes per decimal gigabyte. Those steps reduce to Mbps multiplied by 0.45.
This is a capacity conversion, not a service-specific usage estimate. A 100 Mbps connection can carry an ideal 45 GB in an hour, but a video stream may request only a small fraction of that capacity.
Use the result carefully
Practical hourly data calculations
The conversion is useful whenever a rate is expected to remain active for a known period.
10 Mbps camera feed
4.5 GB/hourA continuous 24-hour feed has an ideal raw volume of 108 GB before recorder or transport details.
25 Mbps sustained transfer
11.25 GB/hourA four-hour transfer window can move an ideal 45 GB at that constant rate.
100 Mbps backup link
45 GB/hourA 500 GB backup needs at least 11 hours 6 minutes 40 seconds at full payload rate.
1 Gbps migration link
450 GB/hourStorage and protocol limits often prevent a real migration from sustaining the full 1 Gbps.
Keep rate and usage separate
Common Mbps-to-GB mistakes
The hourly answer describes maximum continuous volume. It should not be read as an automatic bill, data-cap total, or streaming estimate.
- Multiplying by 3,600 without first converting eight bits per byte.
- Treating available connection capacity as continuous actual usage.
- Mixing decimal GB with binary GiB.
- Ignoring idle periods, variable bitrate, packet overhead, and retransmissions.
- Applying the calculation to several devices without checking whether their rates overlap in time.

Common questions
Good to know.
Why is the multiplier 0.45?+
A megabit is divided by eight to get megabytes, multiplied by 3,600 seconds, then divided by 1,000 MB per decimal GB.
How many GB per hour is 10 Mbps?+
A continuous 10 Mbps rate moves an ideal 4.5 decimal GB per hour. Real payload volume is usually lower when the link is idle or carrying protocol overhead.
How much data can 1 Mbps transfer in a day?+
At a constant ideal rate, 1 Mbps equals 0.45 GB per hour and 10.8 GB over 24 hours.
Is this the same as streaming data usage?+
No. This calculation assumes the connection is fully occupied. A streaming service uses a variable media bitrate that can be much lower than the available connection speed.
Does 100 Mbps always transfer 45 GB every hour?+
No. It reaches 45 GB only if the payload rate stays at 100 Mbps for the entire hour. Server limits, Wi-Fi, overhead, pauses, and other traffic reduce the actual amount.
