Convert internet and transfer rates between bit/s, Mbps, Gbps, MB/s and binary KiB/s or MiB/s. Clearly distinguish bits, bytes and decimal or binary prefixes.
Definitions: NIST binary and decimal prefixes ↗. This converts a supplied rate; it does not measure your internet connection.
Your rates are never uploaded. All conversion runs locally in your browser using exact integer fractions before display rounding. No account, remote API, speed-test traffic or saved input history is needed.
Divide by 8: 100 Mbps (100 Mbit/s) is exactly 12.5 MB/s. Both use decimal prefixes. Uppercase B means bytes; bit and the common abbreviation b mean bits.
MB/s uses 1,000,000 bytes per second. MiB/s uses 1,048,576 bytes per second. This converter keeps decimal and binary units separate and includes prefixes through exa and exbi.
No. It only converts the rate you enter. Actual file transfers can be slower because of protocol overhead, other traffic, server limits and fluctuating throughput. No network speed test is performed.
One byte is exactly 8 bits. Decimal prefixes use powers of 1000 and binary prefixes use powers of 1024. Arithmetic uses exact fractions; the main display is rounded to your chosen 2–12 significant digits and marked ≈ when rounded. Exact target values are also shown.
Nonnegative decimals and scientific notation, up to 120 digits, 180 characters and exponents from −500 to 500. Zero and fractional rates are valid. Negative values, commas and unit names in the numeric input are rejected.
No. Your inputs stay in this browser page and are not persisted. Only the website theme preference is saved. Copy and report download happen only when you choose.
