Data Rate Unit Converter

POSThttps://rftools.io/api/py/v1/calculate

Slug data-rate-units. Convert data rates instantly: bps ↔ kbps ↔ Mbps ↔ Gbps and bytes/sec. Includes presets for UART (9600 bps), CAN (1 Mbps), Ethernet (100 Mbps), and GbE. Also converts baud rate to kbps.

Inputs

Send every one of these in inputs, in the units shown. Most are required: a call without one is refused (400) and costs nothing; one the calculator can do without takes the default shown. An input outside its range is still computed and flagged in the provenance.

Inputs of data-rate-units
Name	Unit	Range	Default	Description
bpsnumber	bps	at least 0	1000000	Data Rate

Outputs

Returned in values, by key. A value that is unbounded or undefined is null.

Outputs of data-rate-units
Field	Unit	Description
kbps	kbps	Kilobits/sec
mbpsheadline	Mbps	Megabits/sec
gbps	Gbps	Gigabits/sec
bytesPerSecond	B/s	Bytes/sec
kBps	kB/s	Kilobytes/sec
mBps	MB/s	Megabytes/sec

Calling it

Calculate: one call, the request and response in full, and its errors.
Batch: this calculator with others, or a sweep, in one request.
Solve for a target: the value of one input that brings an output to a target.
