About this tool
- 1
Enter a value
Type a number into any unit field such as bytes, KB, MB, GB, or TB.
- 2
View conversions
All other units update instantly with both binary (KiB, MiB) and decimal (KB, MB) results.
- 3
Switch to bit rates
Toggle to bit-rate mode to convert between bps, Kbps, Mbps, and Gbps.
- Remember that 1 KB equals 1000 bytes (decimal), while 1 KiB equals 1024 bytes (binary). The tool shows both.
- Use bit-rate mode to convert your internet speed (Mbps) into actual download rates in MB per second.
- When estimating storage, convert your file sizes to the same unit before adding them up to avoid errors.
- Conversion between bytes, KB, MB, GB, TB, and PB
- Both decimal (SI) and binary (IEC) unit systems
- Bit-rate conversions for network speed calculations
- Real-time updates as you type
- Convert file sizes to estimate how many files fit on a USB drive or cloud storage plan
- Translate ISP speed ratings in Mbps to real-world download speeds in MB/s
- Compare storage specifications across devices using consistent units
- Calculate bandwidth requirements for streaming or file transfer operations
In the decimal (SI) system used by storage manufacturers, 1 GB equals 1000 MB. In the binary (IEC) system used by operating systems, 1 GiB equals 1024 MiB. The tool shows both so you can compare.
Divide your file size in megabits by your speed in Mbps. For example, a 800 MB file is 6400 Mb, so on a 100 Mbps connection it takes about 64 seconds.
