Data Transfer Rate Converter — Convert Network and Storage Speeds
The Data Transfer Rate Converter is a free, instant-use tool for converting between 13 data speed units with an integrated transfer time calculator. Whether you're comparing ISP speeds, sizing network infrastructure, benchmarking storage devices, or estimating download times, this tool handles the confusing bits-vs-bytes and decimal-vs-binary distinctions automatically.
All calculations run entirely in your browser. No data is sent to any server.
Supported Units
- bit/s (bps) — The fundamental unit of data rate. Used as the base for all other units.
- Kbit/s (Kbps) — Kilobits per second. 1,000 bps. Used for low-bandwidth connections like dial-up modems.
- Mbit/s (Mbps) — Megabits per second. 1,000,000 bps. The standard unit for internet speed advertising. A 100 Mbps connection can download at about 12.5 MB/s.
- Gbit/s (Gbps) — Gigabits per second. Used for fiber optic connections, enterprise networking, and modern Ethernet.
- Tbit/s (Tbps) — Terabits per second. Used for backbone network links and data center interconnects.
- Byte/s, KB/s, MB/s, GB/s, TB/s — Decimal byte-based rates (1 KB = 1,000 B). Used by download managers, file transfer programs, and storage benchmarks.
- KiB/s, MiB/s, GiB/s — Binary byte-based rates (1 KiB = 1,024 B). Used in some operating systems and technical contexts. Important for accurate storage calculations.
Bits vs Bytes
The most confusing aspect of data rates: ISPs advertise in bits (Mbps), but downloads show in bytes (MB/s). Since 1 byte = 8 bits, divide the ISP speed by 8 to get the download speed. A 100 Mbps plan maxes out at 12.5 MB/s downloads.
Transfer Time Calculator
This tool includes a built-in transfer time estimator showing how long it takes to transfer common file sizes (1 GB, 10 GB, 100 GB, 1 TB) at the entered speed. This is ideal for planning backups, estimating download times, and capacity planning.
