Instantly convert Megabits per second (Mbps) into Gigabytes per day. Accurate, free bandwidth-to-data-usage calculator for internet plans, servers, CCTV and data caps.
Convert Mbps to Data Usage
Enter a connection speed to get an instant, precise estimate of how much data it can transfer per day and per month.
Bandwidth Converter
Enter the speed to see the converted data usage
How many hours a day the connection is transferring at this speed. Use 24 for a theoretical maximum, or a lower figure for realistic usage.
Converted Data Usage
Decimal (SI) Gigabytes, based on 1 GB = 10⁹ bytes
Common Mbps to GB/day Conversions
Standard conversions at 100% utilisation (connection active 24 hours a day) for quick lookup when planning data caps, server bandwidth or storage for continuous streams.
| Speed (Mbps) | Data Per Day (GB) | Common Use Case |
|---|---|---|
| 5 Mbps | 54 GB | Single HD video stream, 24/7 |
| 10 Mbps | 108 GB | IP security camera at high bitrate |
| 25 Mbps | 270 GB | Entry-level home broadband |
| 50 Mbps | 540 GB | Multi-device household streaming |
| 100 Mbps | 1,080 GB | Standard fibre broadband plan |
| 200 Mbps | 2,160 GB | Small office internet connection |
| 500 Mbps | 5,400 GB | Busy shared office or NVR array |
| 1000 Mbps (1 Gbps) | 10,800 GB | Data centre or ISP backbone link |
Mbps to GB Per Day FAQ
Everything you need to know about converting connection speed into daily and monthly data usage.
Multiply the Mbps value by 10.8 to get Gigabytes per day at 100% utilisation. This comes from converting bits to bytes (divide by 8) and seconds to a full day (multiply by 86,400), which combine to a factor of 10.8. For example, 100 Mbps equals 1,080 GB per day.
Internet Service Providers advertise connection speed in Megabits per second (Mbps) because networking standards define link rates in bits. File sizes and data caps are measured in Gigabytes (GB), which use bytes. Since 1 byte equals 8 bits, you must divide by 8 before converting to a daily or monthly total.
Mbps (lowercase b) means Megabits per second and is used for connection speed. MBps (uppercase B) means Megabytes per second and is used for file transfer size. There are 8 bits in a byte, so 100 Mbps equals 12.5 MBps.
No. The Mbps to GB per day figure is a theoretical maximum assuming the connection is fully utilised for 24 hours. Real-world usage is almost always lower due to idle time, network congestion and devices not saturating the link, so this calculator lets you adjust active hours per day.
