Bits, Bytes & Bandwidth Converter
Convert bytes, megabytes, megabits, Mbps, MB/s — SI and IEC units with transfer-time estimates.
About this tool
One number in, every common unit out. Switch between data size (KB, MB, GiB, bits) and transfer rate (Mbps, MB/s). See SI decimal and IEC binary side by side, plus how long a download takes at a given speed.
What you get
- SI (1000) and IEC (1024) storage units from a single input
- Bit/s and byte/s rates with per-minute and per-hour totals
- Estimated time to transfer 100 MB, 1 GB, 10 GB, and 100 GB
How to use
Pick Data size or Transfer rate, enter a value, choose the input unit, then read or copy any row in the results table.
FAQ
How many MB in a GB — SI vs binary?
SI uses 1000-based steps (1 GB = 1000 MB), while IEC binary uses 1024 (1 GiB = 1024 MiB). The tool shows both side by side from one input.
How to convert Mbps to MB/s?
Enter your link speed in megabits per second and read the equivalent megabytes per second plus hourly and daily transfer totals.
What is the difference between MB and MiB?
MB usually means 10⁶ bytes (decimal); MiB means 2²⁰ bytes (binary). Storage labels and network speeds often mix the two—compare both columns to avoid mistakes.
How long to download 1 GB at 100 Mbps?
Enter 100 Mbps as a transfer rate and check the estimated time rows for 100 MB, 1 GB, 10 GB, and 100 GB payloads.
