I've got a simple question:
When I multiply two variables(mm x N), the result always is in Joule (energy), but I want it to always be in Nm (torque):
I know, that its possible to change the Unit from J by manually typing "N*m". But to do this in every line is not very nice. I don't use the unit joule at all. Is there a way to set N*m as the default unit in Express 4?
I don't believe there is.
Mathcad does leave the cursor in the right place to simply backspace once to delete the "J" an type your unit of choice:
There is a way...if you're using real Mathcad, that is Mathcad 15 (or many earlier versions). Simply navigate to the "Tools" menu and select "Worksheet Options", then select "Custom" from the "Default Units" list and then remove "Energy" from the "Derived Units" box and insert "Torque" and set it to Newton-meter...
Now the default will always present the result in N*m units.
