There is a HUGE 'but'...

Assume there is a machine, which measures something. Inside the box is a 
mechanism, which includes a deformable spring. The force upon that 
spring is now fed to a dial, which presents the value of deformation in 
units like 'dyne'.

So far so good.

But the scale of the device contains another inscription,  like e.g. 
'magnetic field strength'.

It could also state, that atmospheric pressure is measured or the the 
temperature in the room.

Now you should NOT mix readings from different machines, just because 
all have the same dimension 'dyne'.
