Yup, it is awfully convenient, e.g.:
# For stepper motors:
You have: 280 oz force in # There's no "ozf".
You want: N m # There is a conformability error if the
* 1.9772345 # oz isn't made oz force.
/ 0.5057569 # See: "force" toward end of the manpage.
If you muck up the units by forgetting the "force", it tells you.
Some other examples:
You have: 1 fathom^3 waterdensity # Water mass
You want: tons
* 6.7422197
/ 0.14831911
Water depth equal to one atmosphere: # Water column
You have: atm
You want: ft water
* 33.898538
/ 0.029499797
And a couple I used recently:
# PV Cable: Resistance of 16 m:
You have: 16m/(copperconductivity * 4 mm^2)
You want: ohms
* 0.068965517
/ 14.5
# PV Cable: Power Loss @ 8 amps:
You have: (8 A)^2 * 16m/(copperconductivity * 4 mm^2)
You want: W
* 4.4137931
/ 0.2265625
Beats using a sliderule.
