Auuki Speed readings: What are the units?

[polygonfuture]

A few questions about speed calculation and units:
What are default units of the speed reading in Auuki? Are these in kph, mph or somethinmg else entirely?

Also are these calculated / converted by Auuki into a specific unit or is this something each smart trainer is setting themselves?

Hi,

the trainer reports speed in kph with resolution of 0.01 under the FTMS protocol specification:

Auuki/src/ble/ftms/indoor-bike-data.js

Line 24 in 7443cdd

InstantaneousSpeed: {resolution: 0.01, unit: 'kph', size: 2, type: 'Uint16', present: speedPresent, short: 'speed', },

In Auuki you can switch between 1. the speed as reported by the trainer and 2. the speed estimated from power by the power to speed model in Auuki. The switch is in the settings page under the label Simulation. The estimation model works with m/s. Further you can use the Metric/Imperial toggle under the weight input to convert the speed to either system, so the speed you see is mph or kph, depending on that setting.
