Why do GB and GiB produce different numbers?
GB uses decimal powers of 1000, while GiB uses binary powers of 1024, so the converted values diverge.

About this tool
Convert data sizes across decimal units (KB, MB, GB, TB) and binary units (KiB, MiB, GiB, TiB) from a single input. The tool also outputs total bits for bandwidth-related calculations and clarifies the 1000 vs 1024 scale difference. It is useful for disk planning, CDN transfer estimation, and API payload budgeting. Calculations run instantly and locally in the browser.
Direct Answers
Should I estimate network transfer in bytes or bits?
Storage planning usually speaks in bytes, while bandwidth planning often needs bits and bit-rate conversions.
