[Health 4.4.0] Abillity to convert totalDistance to prefered HealthDataUnit, or list of possible values needed

[thomasmol]

Description

Currently, the totalDistanceUnit is of type HealthDataUnit. This data type has many units, like liters, meters, miles, inches_of_mercury, etc. Obviously only some of these apply to distance as a unit.

I would like to see a list of all the different HealthDataUnit value the totalDistanceUnit can be.

Mainly because I want to convert the value of totalDistance to meters. So some function to convert the totalDistance to some HealthDataUnit would work as well!
