Digital Storage Converters
Convert between bits, bytes, kilobytes, megabytes, gigabytes and terabytes instantly.
Confused about how many photos fit in 1 GB, how many MB in a GB, or whether your download speed in Mbps means fast or slow file transfers? Digital storage conversions come up constantly - checking if a file fits on a USB drive, understanding your phone's storage, comparing cloud plans or calculating how long a download will take. Remember: internet speeds are measured in megabits per second (Mbps) while file sizes use megabytes (MB), and 1 MB = 8 Mb, so a 100 Mbps connection downloads about 12.5 MB per second.
Frequently asked questions
At a typical smartphone photo size of 3-5 MB, you can fit roughly 200-333 photos in 1 GB. RAW camera files at 20-30 MB each fit only 33-50 per GB. Video takes far more space - a minute of 4K video at 400 MB uses most of a GB.
1 GB equals 1000 MB using the standard decimal (SI) definition used by hard drives and most operating systems. Some older systems use 1024 MB = 1 GiB (gibibyte), which is why a '1 TB' drive may show around 931 GB in Windows.
Mbps means megabits per second (download speed) while MB/s means megabytes per second (file transfer rate). Since 1 byte = 8 bits, divide your Mbps speed by 8 to get MB/s. A 100 Mbps connection downloads at about 12.5 MB/s.
1 TB equals 1000 GB. A 1 TB drive can hold roughly 250,000 photos at 4 MB each, 200 hours of HD video at 5 GB per hour, or about 200,000 MP3 songs at 5 MB each.
There are exactly 8 bits in 1 byte. Bits are the smallest unit of digital data and are used to measure network speeds (Mbps, Gbps). Bytes are used to measure file sizes and storage. A standard ASCII character takes 1 byte (8 bits).
