Noticing that changing the units don't recalculate the outputs

@Kcheung42 that's only for auto-computing tools. This isn't set up that way. We'll be looking at adding the global Metric/English switch to make this more straightforward.

Ah right. Looks good then! One thing to note during migration: Be sure to re evaluate conn in between the transactions (tx-data-1, tx-data2 etc), otherwise i ran into an error of missing entities (i.e. ln 92 (sm/t-key->eid conn "behaveplus:tags:safety-conditions")) and the transaction would silently fail.
