Unitless Calculations?

i'm doing a calculation where the units cancel out in an exponential equation.  However, MathCad will not evaluate the equation because the value is unitless.  Is there a way to turn off units in a calculation? If not, is there a way to get around this error?  Thanks

That should work. Could you post a worksheet showing the problem (to post a worksheet, in the edit dialog click on "Use advanced editor" at the top right).

Hi,

the value of L.z shows as 344.177 ft^1.2, so the error message that Mathcad is giving is correct.

The units don't cancel out properly.

If this is an empirical equation then it might be that you have to apply a correction factor,

Otherwise you will need to look at the definition of L.z again
