データ単位変換

Where this converter helps

• Checking the difference between byte-based file sizes and bit-based network speeds.
• Estimating whether media files, backups, or datasets fit inside a storage quota.
• Converting large byte counts into human-readable units for reports and dashboards.

Using the interface

Type a value into any storage unit. The grid recalculates the rest using binary multiples, so one kilobyte is treated as 1024 bytes in this tool.

Practical notes

• Uppercase B means bytes, while lowercase b means bits; eight bits equal one byte.
• Use megabytes and gigabytes for files, and megabits or gigabits when reading many internet speed plans.
• If a vendor uses decimal SI storage, expect small differences from binary-size tools.
